MCQ
particle is dropped from a height and another particle is thrown in horizontal direction with speed of $5 m / sec$ from the same height. The correct statement is
  • ✓
    Both particles will reach at ground simultaneously
  • B
    Both particles will reach at ground with same speed
  • C
    Particle $$ will reach at ground first with respect to particle
  • D
    Particle will reach at ground first with respect to partical
✓

Answer

Correct option: A.
Both particles will reach at ground simultaneously
(a) For both cases $t=\sqrt{\frac{2 h}{g}}=$ constant.Because vertical downward component of velocity will be zero for both the particles.
