Question

A block of mass 2 kg is lying on a rough inclined plane the force needed to move the block up with the plane with a uniform velocity by applying a force parallel to a plane is hundred newton is the force needed to move the block up with an acceleration of 2 metre per second square is

Answer 1

Answer:

C . 96 Newton

Explanation:

According to Newton 2nd law of motion;

Force = mass × acceleration

As we are given that the block is of 2 kg and it is to be moved with an acceleration of 2 m/s^2.

Force =2× 2

= 4 N

total force applied = 100 N

Net force = 100 - 4

= 96 N

So option C is correct
