NEET Physics Question - Work Energy and Power

Rankers Physics

Topic: Work Energy and Power

Subtopic: Kinetic Energy and Momentum

Two masses of 1 g and 4 g are moving with equal kinetic energies. The ratio of the magnitudes of their linear momenta is

1:2

√2:1

4:1

1:16

Kinetic Energy is given by K = ½mv² and Momentum is P=m.v, relation between kinetic energy and momentum is

K= P²/2m so P=√(2mK)

So P1/P2= √(m1)/√(m2)= √1/√4 = 1:2
