The displacement-time graph of two moving particles make angles of 30^ and 45^ with the X -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

By the definition, the slope of displacement-time graph is velocity. i.e., v= v₁ v₂ = ₁ ₂ v₁ v₂ = 30^ 45^ v₁ v₂ = 1 3
