Question

what is acting on a body making at an angle of 30 with the horizontal the horizontal component of the force is 20 Newton find the force​

Answer 1

Answer:

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
