The displacement-time graphs of two moving particles make angles of 30^ and 45^ with the time axis. The ratio of their velocities is

Options

  1. A3 : 2
  2. B1: 1
  3. C1: 2
  4. D1: 3

Correct answer

D. 1: 3

Step-by-step solution

Velocity v = displacement ( s ) time ( t ) From given s-t graph V _ (30^ ) V _ (45^ ) = 30^ 45^ = 1 / 3 1 =1: 3
