Q. A particle $(A)$ is dropped from a height and another particle $(B)$ is thrown in horizontal direction with speed of $5\ m/sec$ from the same height. The correct statement is
A) Both particles will reach at ground simultaneously
B) Both particles will reach at ground with same speed
C) Particle $(A)$ will reach at ground first with respect to particle $(B)$
D) Particle $(B)$ will reach at ground first with respect to particle $(A)$
Explanation
(a) For both cases $t = \sqrt{\frac{2h}{g}} =$ constant
Because vertical downward component of velocity will be zero for both the particles
