Q. A missile is launched at an angle of 60 degree to the vertical with the velocity of sq.root (3GM/4R) from the surface of the earth .(R is the radius of the earth ).Its maximum height from the centre of the earth is aR. Find a*100.(Take sq. root 304=17 and neglect air resistence and the rotation of the earth.)

Recheck the calculation part if you are not getting the correct answer.

There is a mistake in the 3rd line of calculation. You have written 3/(4R)....it should be 3/(8R).
