Problem

A particle can be thrown at a constant speed at different angles. When it is thrown at

15^\circ

with horizontal, it falls at a distance of 10 m from point of projection. For this speed of particle match following two columns.

Column I	Column II
(a) Maximum horizontal range which can be taken with this speed	(p) 10 m
(b) Maximum height which can be taken with this speed	(q) 20 m
(c) Range at $75^\circ$	(r) 15 m
(d) Height at $30^\circ$	(s) None of the above
