A point object is placed infront of a plane mirror as shown in figure. X_(OM) rArr x - co-ordinate of object relative to mirrorX_(IM) rArr x -x-co-ordinate of image relative to mirrorX_(IM) = -X_(OM)differentiating V_(IM) = 0-V_(OM)V_I - V_M = - (V_0 - V_M) Velocity if image relative to mirror = velocity of object relative to mirror. basing on this information answer the questions Two bodies A and B are moving towards a plane mirror with speeds V_A and V_B respectively as shown in fig. The speed of image of A with respect to the body B is

Answer»
