The greatest and least resultant of two forces acting at a point are `29 kg wt.` and `5 kg wt.` respectively . If each force is increased by `3 kg wt.` the magnitude of the resultant of new forces acting at right angles to each other is

A

`45 kg wt.`

B

`35 kg wt.`

C

`25 kg wt.`

D

`15 kg wt.`

Text Solution

Verified by Experts

The correct Answer is:
C
`a+b=29,a-b=5,a^(1)=a+3,b^(1)=b+3`
`R'=sqrt(a^(1^2)+b^(1^2))`
