Question

solution: as given in question

weight of block is 7N and downward push is 4N

the total force exerted on a block is 7+4=11N

according to Newton's 3rd law table also exert the equal force in opposite direction so table exert 11N force on block to balance it.

Answer 1

Explanation:

the force exerted of by the table on the block is normal force(n)

by the FBD (force body diagram)

N= f+mg

N= 4+7

N=11 Newton
