Question

20

Answer 1

Answer:

The correct option is;

(A) 1 m/s

Explanation:

Given that Ramu and Somu are running towards North with 3 m/s and 4 m/s respectively.

Their friend Srinu is running towards South with a speed of 2 m/s

The magnitude of the relative velocity of Ramu with respect to Ramu is found as follows;

Velocity of Ramu = 3 m/s North ↑

Velocity of Srinu = 2 m/s South↓ = -2 m/s North ↑

Relative velocity of Ramu to Srinu = Velocity of Ramu North + Velocity of Srinu North

Relative velocity of Ramu to Srinu = 3 m/s + (-2) m/s = (3 - 2) m/s = 1 m/s

Relative velocity of Ramu to Srinu = 1 m/s.
