There are four forces acting on a block as shown in the figure ,The magnitude and direction of the net force acting on it is _______.

A

150 N , towards right

B

100 N , upwards

C

70 N , towards right

D

70 N , towards left

Text Solution

Verified by Experts

The correct Answer is:
C
Since the upward and downward forces are equal in magnitude but opposite in direction, the net vertical force acting on the body becomes zero and the body does not move either in upward or in downward direction
Net horizontal force acting on the body is F = 150 80 = 70 N and in the direction ofgreater force i.e. towards right side. Therefore, the body moves towards right
Hence the correct option is (c).
