Question

applied The block weighs 50N and the force is 20N. Calculate the normal force in each case 37°​

Answer 1

Explanation:

Correct option is

A

The normal force is less than 50N

Given : F=20 N W=50 N

Thus vertical component of the force F

v

=F sin30

o

=20×0.5=10 N

Let the normal force exerted on the block by the surface be N.

∴ F

v

+N=W

OR 10+N=50 ⟹N=40 N

Hence option A is correct.
