Two protons are travelling. along the same straight path but in opposite directions. The relative velocity between the two is ………(a) c(b) \(\frac{C}{2}\)(c) 2c (d) 0 |

Answer» Correct answer is (a) c One of the velocity V1 = V; Other velocity V2 = -V Relative velocity (Vrel) = \(\frac{V_1 - V_2}{[1 + \frac{V^2}{C^2}]}\) = \(\frac{V- (-V)}{[1 + \frac{v^2}{C^2}]}\) = \(\frac{2v}{2}\) V = C Vrelative = C |
