11th Physics Monthly Test - 4 ( Laws of motion )-Aug 2020

Time : 2.00 Hours

Part - A

Generic 5 - Answer All Question

Write an explanation on Newton's laws

Briefly explain how is a vehicle able to go round a level curved track. Determine the maximum speed with which the vehicle can negotiate this curved track safely.

What are concurrent forces? State Lami's theorem.

Prove Impulse - Momentum equation.

Consider a circular leveled road of radius 10m having coefficient of static friction 0.81. Three cars (A, B and C) are travelling with speed 7 ms^-1, 8m s^-1 and 10 ms^-1 respectively. Which car will skid when it moves in the circular level road? (g = 10 m s^-2).

Consider an object moving on a horizontal surface with a constant velocity. Some external force is applied on the object to keep the object moving with a constant velocity. What is the net force acting on the object?

Describe the method of measuring angle of repose.

Briefly explain 'rolling friction.

Derive an expression for the acceleration of the body sliding down a frictionless surface.

Identify the free body diagram that represents the particle accelerating in positive x direction in the following.

Using Newton's laws calculate the tension acting on the mango (mass m = 400g) hanging from a tree.

State Newton's three laws and discuss their significance.
