A body is projected at an angle of 60° with the horizontal. If its kinetic energy at its maximum height is 10 J, then the height at which its potential energy and kinetic energy have equal values is (consider potential energy at the point of projection to be zero)
Text Solution
Verified by ExpertsThe correct answer is:
B
two third of the maximum height
KE at maximum height
...(i)
When PE = KE
mgh = 20 = ...(ii)
from (i) and (ii)
