A contant force starts acting on a body of mass m at rest. The velocity v acquired in treveling a specific distance depends on m as

Options

A. `c(1)/(m)`
B. `vprop(1)/(sqrtm)`
C. `vpropm`
D. `vpropsqrtm`

Answer

B

Explanation

`u=0` , `a=F//m` , Apply `v^(2)=u^(2)+2as` .
` implies V^(2)=0^(2)+(2F)/(m)s implies v^(2)=(2Fs)/(m)` .
`implies v^(2)prop(1)/(m) implies vprop(1)/(sqrtm)` .
