Answer

$0.75N$

Work Step by Step

Since the force applied to the block is less than the minimum force needed for the object to overcome kinetic friction (1.50N), the frictional force equals the value of the applied force. Therefore, the force of friction on the object is the same as the applied force, 0.75N.
