Question

A block of mass 1 kg is held against a smooth wall by applying a horizontal force F of 5 N on the block and
another force F, parallel to plane of the wall. The value of F, is
(A) 5 N
(B) 10 N
(C) 55N
(D) 15 N​

Answer 1

Answer:

The correct Answer is B (10N)

Answer 2

Answer:

10 N

Explanation:

Since, block is held against the wall so

F2 and mg are balanced, and since Mg acts downwards towards the centre of the earth,

by this,

mg=1*10=10

( taking g as 10 )

now,

F2 and Mg are balancing each other, therefore, the value of F2 is 10.

I hope it solves your problem.
