An object is projected with kinetic energy 
from a point 
at an angle 
with the horizontal. The ratio of the difference in kinetic energies at points 
and 
to that at point 
(see figure), in the absence of air friction is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
At A: 
, angle 
.
At B (highest point): 
, so 
.
At C (same level as A): by energy conservation, 
.
.
Ratio 
, i.e., 
.
