Explanation:
Given that,
The force of gravity is 30 N
Normal force is 30 N
Applied force is 6 N (right)
Net force is 20 N (left)
We need to find the friction force of the object. We know that friction is an opposing force. It always acts in the opposite direction of the applied force. The magnitude of applied force and friction force is same but direction is different.
Hence, frictional force is 6 N to the left.
