A block is dragged without acceleration in a straight-line path across a level surface by a force of 6 N. What is the force of friction between the block and the surface?
A)less than 6 N
B)6 N
C)more than 6 N
D)need more information

Since the block is moving without acceleration, the net force acting on it is zero. This means the force of friction exactly balances the applied force of 6 N, making the force of friction also 6 N.
