Question

7. Which of the following pairs of forces cannot be added to give a resultant force of 4 N?
1) 2 N and 8 N
2) 2 N and 2N
3) 2 N and 6 N
4) 2N and 4N
5)1N and 5N
​

Answer 1

Answer:

1) 2N and 8N

Explanation:

It is because maximum Resultant force will be (8+2)=10N and Minimum will be (8-2)=6N. 4N does not lie within this value range Therefore It is not possible to have it as resultant.
