Question

Two masses of 10gm and 40 gm are moving with equal kinetic energies. The ratio of the magnitudes of their linear momentum is

Answer 1

Explanation:

ATQ , k1 = k2 i.e. 1/2 × 10 × v1^2 = 1/2 × 40 × v2^2

v1/v2 = 2

Let the linear momentum be p1 and p2

p1/p2 = 10 × v1 /40 × v2 = 1/2

Hence answer is 1/2.
