Question
CBSEENPH11020603

A stone falls freely under gravity. It covers distances h1 , h2 and h3 in the first 5 seconds, the next 5 seconds and the next 5 seconds respectively. The relations between h1, h2 and h3 is,

  • h1 = 2 h2 = 3 h3

  • h1straight h subscript 2 over 3 space equals space h subscript 3 over 5

  • h2 = 3 h1 and h3 = 3 h2

  • h1 = h2 = h3

Solution

B.

h1straight h subscript 2 over 3 space equals space h subscript 3 over 5

Relations between h1, h2 and h3 is,

straight h subscript 1 space equals space straight h over 3 space equals space straight h subscript 3 over 5

rightwards double arrow space straight h subscript 1 space colon space straight h subscript 2 space colon straight h subscript 3 space equals space 1 colon space 3 colon space 5
