Question

A Body Is Acted upon By A constant torque In 3seconds its angular momentum changes from L to 7l The magnitude of torque is​

Answer 1

Answer:

Given That, dt=3 second

L1=L and L2=7L

so the torque is given by

T=dl/dt =(L2-l1)/dt = (7L -L)/3 =6L/3 = 2L

So the magnitude of the torque is T=2L, N-m
