Question

Three people are trying to move a box. Which set of forces will result in a net
force on the box of 20 N to the right?
CAN SUM1 please help

Answer 1

Answer :-

The person who is exerting 55N will move the  box 20N to the right (option B).

Reason :-

• The total force by the two people in the left side is .. 17 N + 16N  = 33N.
• So, the net force acting on the box is, 55N - 33N = 20N.
• The box will move towards the right because greater force is acting there.
