Question

A 20N was applied to the right of an object, also, 25N and 23N was applied to the left. What is the sum of forces? Show workout 

Answer 1

$25 + 23 - 20 \\ 48 - 20 \\ 28n$

Answer 2

Given:

Force applied to the right side of the object = 20N

Forces applied to the left side of the object = 25N and 23N.

To find:

The sum of forces acting on the body.

Solution:

Let us consider the direction to the left as positive, then the director to the right side will be considered as negative.

Sum of forces applied to left side = 25 + 23 N = 48N

Sum of forces when a force of 20 N is applied in the right side = 48- 20N = 28N

The sum of forces applied on the object is 28N.
