Numerical Problem No. 4.4 (Turning Effect of Forces) Physics SSC - I (Class 9)

A force of 100 N is applied perpendicularly on a spanner at a distance of 10 cm from a nut. Find the torque produced by the force. Ans. (10 Nm)

Given:  

Magnitude of  Force  = F =   100 N

distance from the nut  = L =   10 cm = 0.1 m

To Find:

Torque = T = ? Nm

Solution:   

The formula for the Torque T is

T =  F ｘ L

by putting values

T = 100 N ｘ 0.1 m

T = 10 N m

Thus Torque produced by the force is 10 Nm
