Answer 1

Given Information:

Find the torque acting on a rotating body, if it's angular momentum changes from 5 kgm²/s to 8 kgm/s in 4 seconds.

Solution:

We know that,

T = △ T

△L

Where,

• L denotes distance
• F denotes magnitude

$• \: T=\underline{L^{f} - L^{1} }\\• \: T=\underline{8 - 5} \\ \: \: \: \: \: \: \ \: \: \: \: \: {4 - 0}\\ \\ • \: T=\underline{3} \ \: \: \: \: \: \: \: \: \: \: \:\\4$

Therefore, torque acting on a rotating body is 3/4Nm
