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

Options

A. `45 kg wt.`
B. `35 kg wt.`
C. `25 kg wt.`
D. `15 kg wt.`

Answer

C

Explanation

`a+b=29,a-b=5,a^(1)=a+3,b^(1)=b+3`
`R'=sqrt(a^(1^2)+b^(1^2))`
