Question

A particle of mass m is moving On a circular path of radius R with uniform speed V rate of change of Linear Momentum is
A)Zero
B)Independent of speed
C)Promotional to radius r
D)Proportional to v2

Answer 1

Answer:

d............no is your correct answer

Answer 2

Answer:

D

Explanation:

As we know....

dp/dt= F (F-centripetal force)

particle on a circular motion then,

F = MV² / R

then

dp/dt = MV² /R

dp/dt proportional to V²
