A block of mass 4 kg is kept on ground. The co-efficient of friction behween the block and the ground is0.80 An external force of magnitude 30 N is applied parallel to the ground The resultant force exertedby the ground on the block is:

Answer»

To make the block move you need to apply force aboveùmgwhere u is 0.8So the minimum force comes out to be = 31.36 NewtonSo if u apply 30 Newton the ground will apply 30 NEWTON!

when o say if u can do the question numerically then solve
