In case of any Query or Question regarding 11th class physics Chapter 1 Measurements Short Question answers then please leave your opinion below in comments section respectively.

Since the masses of the balls are not the same, therefore, the inertial forces are not same on both the balls. F1 > F2 NCERT Solutions for Class 12 Business Studies Chapter 1 प्रकृति और प्रबंधन का महत्व. Q8. = (3 + 2v2)kg ms-1 = \(\left(\frac{1}{20} \mathrm{kg}\right)\left(-5 \mathrm{ms}^{-2}\right)\) Yes, the balls will start rolling in the direction in which the train was moving. 11th class physics Chapter 1 Measurements Short Question Answers. Suppose the velocity of the boy on the cart, as the cart starts moving is v. Third It is the world of middle-sized things from molecules at one extreme to the Earth at the other.This is all fundamental physics which is the heart of science. At point p the fields are added to give the net field.

Think What Will Happen, If The Literacy Rate Of India Grow Rapidly In Future, Then Our Country Will Develop More Than Now For Sure. The dense population indicates strong electric field and real populate indicates weak field.

⇒ v2 = – 1.5 ms-1 Get hundreds of questions to prepare and get better marks in 9th physics 0. In other words,

Explain why? d. For large C, we can hold large Q. wo basic properties of electric charge are :-, Answer – Coulomb law in vector form is more informative than is scalar form. So We Are Here To Fulfil Crore’s Of Dreams. F1 = m1a1 = 2 × 5 = 10N

Q10. To Download 9th Class Physics Unit/Chapter 1 Short question answers Click: 9th Class Physics Chapter 1 Solved Numericals. Answer – Electric field intensity at a point in an electric field is electric force per unit test charge placed at a point. = 0.02kg × (+150ms-1) + 2kg + v2 ms-1 Force, F2 = ma2 = \(\frac{50^{\circ}}{1000} \times(-30)\) = – 1.5 N Here, m = 0.4 kg, u = 10 m/s Thus, the balls will move with different speeds. The SI unit is voltmeter and it is a scalar quantity. According to law of conservation of momentum, we have or, v2 = \(-\frac{4}{7 \cdot 5}\) = – 0.533

The balloon moves vertically upwards (reaction). You just need to click the below image to see the notes. Here are English medium and urdu medium 9th class physics short questions notes in PDF. For example – In a parallel plate capacitor, V <= E max.

A bullet of mass 20 g is horizontally fired with a horizontal velocity 150 ms-1 from a pistol of mass 2 kg.

Answer – Each charge produces its own field as if other charges were not present. d which means Q <= C E max. Students can find here the CBSE Class 9 Science (Physics) Practice Paper to get an idea of important questions to be prepared for the annual exam 2019. Mass of gun, m2 = 7.5 kg Answer:

Why does an athlete run a certain distance before taking a leap? If a test charge Q experiences a force F when placed at rest at the point, the force per unit test charge E given by.

43 v = 200 If the initial velocity of the bullet is 200 m/s, calculate the speed with which the gun recoils.

But the same force will produce a negligible change in the motion of a bus, because in comparison to the bicycle, a bus has more tendency to oppose any change in its state of motion because of its larger mass i.e., the bus has more inertia than the bicycle. An athlete runs a certain distance before taking a leap so that the inertia of motion of his body at the time of leaping may help him in his muscular efforts. Q2.

S.I unit of electric dipole moment is coulomb metre. For pistol: m2 = 2kg, u2 = 0 ms-1, Required fields are marked *. Important Short Questions | Physics | Class 12 | Electrostatic (Chapter 1) | 2020 Board Exams (CBSE), Answer – The charge per unit area of surface is known as surface charge density.

= 200 kg ms-1

they are originated from positive charge and enters the negative charge. Velocity of bullet, v1 = 200 m / s (II) it indicates that Coulomb force is a central force either X along the line joining the two charges. This chapter is all about the solution. There is some helpful content against each chapter of 10th class physics book.
