momentum of A = mv
momentum of B = 2m*2v=4mv
ratio = mv/4mv
=1:4
momentum of B = 2m*2v=4mv
ratio = mv/4mv
=1:4

Momentum = p = mv
pA / pB = (mA / mB) × (vA / vB)
= (m / (2m)) × (v / (2v))
= 1 / 4
Ratio of their momentum is 1 : 4
pA / pB = (mA / mB) × (vA / vB)
= (m / (2m)) × (v / (2v))
= 1 / 4
Ratio of their momentum is 1 : 4
