Note: - You are attempting question 2 out of 12An object A moving with a speed 0.65c relative to earth and another object B movingwith a speed 0.75c relative to the object A. Calculate the speed of the object B relative tothe earth if these objects travelling in same direction.(a) 1.000(b) 0.20c(c) 0.94c(d) 0.10c |

Answer» (a) 1.00 cExplanation:You just have let that the OBJECT A is moving with 0.65c in relative to another object which itself is moving with 0.75c relative to Earth. Please NOTE that this speed of A is not POSSIBLE according to quantum mechanics.If both objects are moving in same direction, then speed of object B with respect to Earth will surely become 0.65c + 0.75c i.e., 1.40cBut according to Einstein, NOTHING can travel faster than the speed of light, 1.40 c speed isn't possible itself. HENCE, the object B will appear as if to moving at the speed of light, from Earth. |
