Question

14:
The angle of inclination of the plane at which the body placed above the plance starts to slide down
automatically due to component of weight acting along the plane is called as
coefficient of friction
O angle of repose
none of the given options
angle of friction​

Answer 1

Answer:

correct option is (A)

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

A body on an inclined plane just tends to slide down if the angle of inclination is equal to the angle of friction because when angle of inclination is equal to angle of friction, the component of weight parallel to the plane is just sufficient to overcome the frictional force. Thus both assertion and reason are correct and reason is the correct explanation for assertion.
