A stone, Q is thrown with velocity U at an angle of 75o to the horizontal. Another stone R is thrown with the same velocity U but with an angle of 15o to the horizontal. The ranges covered by the stones will be
A
greater for Q
B
greater for R
C
the same for Q and R
D
greater for the heavier of the two stones
correct option: c
Range = \(\frac{U^2sin2\theta}{g}\)

RangeQ = \(\frac{U^2sin150}{g}\)

RangeR = \(\frac{U^2sin30}{g}\)

Since, sin30o = sin150o

therefore, RQ = RR
