The sum of two forces at a point is 16N. if their resultant is normal to the smaller force and has a magnitude of 8N, then two forces are

A

2N

B

4N

C

6N

D

7N

Text Solution

Verified by Experts

The correct Answer is:
C
`x=y=16`
Also, `y^(2)=8^(2)+x^(2)`
or `y^(2)=64+(16-y)^(2) [:' X= 16-y]`
or `y^(2) =64+256+y^(2)-32y`
or `32y=320` or `y=10N`
`:. X+10=16` or `x=6N`
