The vertical component of force should be equal to wieght of the object

FSin45 = mg
F/√2 = 4×10
F = 40√2 N

Force required is 40√2 N

"According to the given details, the block A of mass 4kg is to be kept at rest against a smooth vertical wall by applying a force F.

Then the required force is calculated below.  In fact, the vertical aspect of force is equal to the weight of an object. It is given as mg= FSin45.

F/√2 = 4×10

F = 40√2 N

Hence, the required force is 40√2 N.
