If a projectile has a constant initial speed and angle of projection, find the relation between the changes in the horizontal range due to change in acceleration due to gravity.

Explanation

`R=(u^2sin 2theta)/(g)`
`R_1=(u^2 sin2theta)/(g_1) , R_2=(u^2sin2theta)/(g_2) therefore (R_1)/(R_2)=(g_2)/(g_1)`
Hence, horizontal range is inversely proportional to the acceleration due to gravity.
