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) more than 6 N
B) less than 6 N
C) 6 N
D) need more information to say

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.
