Which pair of the following forces will never give resultant force of `2 N`?

A

1 N and 3 N

B

2 N and 2 N

C

1 N and 1 N

D

1 N and 4 N

Text Solution

Verified by Experts

The correct Answer is:
D
The forces 1 N and 4 N will never give the resultant force of 2 N.
In (c ) 1 N+ 1 N =2 N if they are acting in the same direction. In (a) 3 N- 1 N =2 N, if they act along the same straight line but in opposite direction.
In (b) two forces 2 N and 2 N will have a resultant equal to 2 N if the angle between them is `120^(@)`.
