In length contraction , L=Lo sqrt 1_v^2/c^2 ,,,,,,, what does this sqrt v^2/c^2 mean ???????????

Answer 1

it is the famous equation which give the relation b/w the mass and energy. E=MC^2


here if the body moves with velocity = speed of light then it can change


so 1-v2/c2
if the velocity =speed of light
then v2/c2 will be 1 so 1-1 =0
so
mass /0 =infinity

hope it will help you
