Question

A block is pulled by a force of 20N at an angle of 30 degrees from the horizontal. Identify which of the following statement best describes the force between the block and the surface???​

Answer 1

Explanation:

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
