A monkey is sitting on a tree limb. The limb exerts a normal force of 48 N and a frictional force of 20 N. Find the magnitude of the total force exerted by the limb on the monkey.

Text Solution

Verified by Experts

The correct Answer is:
B
The limb exerts a normal force 48 N and frictioN/A, force of 20 N.


Resultant magnitude of the force `R= sqrt( (48^2+20^2))`
` = sqrt(2304+400) `
` sqrt(2704) = 52 N`.
