Two balls are projected from points A and B in vertical plane as shown in figure. AB is a straight vertical line. The balls can collide in mid air if `v_1//v_2` is equal to

A

a. `(sintheta_1)/(sintheta_2)`

B

b. `(sintheta_2)/(sintheta_1)`

C

c. `(costheta_1)/(costheta_2)`

D

d. `(costheta_2)/(costheta_1)`

Text Solution

Verified by Experts

The correct Answer is:
D
d. If the particles collide in mid air, they travel same displacement
in horizontal direction. So their velocity components along
horizontal should be same, i.e., `v_1costheta_1 = v_2costheta_2`.
