Given below are two statements: In the light
of the given statements, choose the correct
answer from the options given.
Statement I: Mass is a measure of inertia of the body.
Statement II: Greater the mass, greater is the force required to change its
state of rest or of uniform motion.
of the given statements, choose the correct
answer from the options given.
Statement I: Mass is a measure of inertia of the body.
Statement II: Greater the mass, greater is the force required to change its
state of rest or of uniform motion.
View answer and explanation
Correct option: A
Both statement I and II are correct
Option A (Both statement I and II are correct) is correct because mass is indeed a measure of inertia, and a greater mass requires a greater force to change its state of motion due to its higher inertia.

(A): Two solid cylinders of different masses and radii take same time to roll down an inclined plane without slipping.
(R): Moment of inertia of two solid cylinders of different masses and radii about their natural axes are different. Given below are two statements:
Statement I: An elevator can go up or down with uniform speed when its weight is balanced with the tension of its cable.
Statement II: Force exerted by the floor of an elevator on the foot of a person standing on it is more than his/her weight when the elevator goes down with increasing speed.
In the light of the above statements, choose the correct answer from the options given below: A particle is projected with a velocity at an angle of . At the highest point, it explodes into three particles of equal masses. One goes vertically upwards with a velocity , the second particle goes vertically downwards. What is the velocity of third particle? A loaded coal wagon is moving on a level track at . Suddenly of coal is dropped out of the wagon. The final speed of the wagon is Assertion : Mass is a measure of inertia of the body in linear motion.
Reason : Greater the mass, greater is the force required to change its state of rest or of uniform motion. An air tight cage in which a bird is sitting is suspended from a spring balance. If the bird starts flying, then the reading of the balance will
