According to Newton's first law, the block will remain at rest or move with a constant velocity in a straight line unless acted upon by an unbalanced force. Since the block is not accelerating, the force of friction must be equal in magnitude and opposite in direction to the applied force of 6 N. Therefore, the force of friction is 6 N.
