A projectile is fired from the surface of the earth with a velocity of 5 
and angle 6 with the horizontal. Another projectile fired from another planet with a velocity of 3 
at the same angle follows a trajectory which is identical with the trajectory of the projectile fired from the earth. The value of the acceleration due to gravity on the planet is 
in 
is 
Given 
Text Solution
Verified by ExpertsA
The equation of trajectory is
where 6 is the angle of projection and 
is the velocity with which projectile is projected.
For equal trajectories and for same angles of projection,
constant
As per question, 
where 
is acceleration due to gravity on the planet.
