1.	For a constant initial speed and for constant angle of projection of a projectile the change dR in its horizontal range R due to a change dg in value of gravitational acceleration g is governed by the relation:
Answer» `(dR)/(R)=(dg)/(G)` `(dR)/(R)=(-dg)/(g)` `(dR)/(g)=(dg)/(R)` `(dR)/(g)=(-dg)/(R)` ANSWER :B
