A stone falls freely under gravity. It covers distances h1,h2h_1, h_2 and h3h_3 in the first 5 seconds, the next 5 seconds and the next 5 seconds respectively. The relation between h1,h2h_1, h_2 and h3h_3 is

Options

  1. Ah1=2h2=3h3h_1=2 h_2=3 h_3
  2. Bh1=h23=h35h_1=\frac{h_2}{3}=\frac{h_3}{5}
  3. Ch2=3h1h_2=3 h_1 and h3=3h2h_3=3 h_2
  4. Dh1=h2=h3h_1=h_2=h_3

Correct answer

B. h1=h23=h35h_1=\frac{h_2}{3}=\frac{h_3}{5}

Step-by-step solution

The relation between h1,h2andh3h_1, h_2 and h_3 is h1=h3=h35⇒h1:h2:h3=1:3:5\begin{aligned}h_1 & =\frac{h}{3}=\frac{h_3}{5}\\ \Rightarrow h_1: h_2: h_3 & =1: 3: 5 \end{aligned}
