Question

The maximum height attained by a projectile is increased by 10% by increasing its speed of projection, without changing the angle of projection. The percentage increase in the horizontal range will be

Solution

Correct option is

10%

 

We know that  The increase δ h in h when v0 changes by δ v0can be obtained by partially differenting this expression. This

                              

  

 Since h is increased by 10 %, 

Therefore,

                   

                       

Thus δR = 0.1 R. Hence also increased by 10%.
