Text Solution

Verified by Experts

The correct Answer is:
B, C, D

(b.,c.,d.) If the particle is projected with velocity `u` at an angle `theta`, then equation of its trajectory will be
`y = x tan theta -(gx^2)/(2 u^2 cos^2 theta)`
We know slope is given by `m = (dy)/(dx)`
Therefore, slope `m = tan theta - (gx)/(u^2 cos^2 theta)`
It implies that the graph between slope and `x` will be straight line having negative slope and a non - zero positive intercept on y - axis.
But `x` is directly proportional to the time `t`, therefore, the shape of graph between slope and time will be same as that of the graph between slope and `x`. Hence, only option (a) is correct, i.e., options (b),(c)and (d) are incorrect.
