Question

A particle when thrown. moves such that it passes from same height at $2$ and $10s$, the height is:

• A. $g$
• B. $2g$
• C. $5g$
• D. $10g$

Answer 1

The correct option is D $10g$

If t1 and t2 are the time when the body is at the same height Then $h=\frac{1}{2}\times g\times t_1\times t_2$$h=\frac{1}{2}\times g\times 2\times 10$h = 10 g

So that the correct option is D
