The relation between [ ε 0 ] and [ μ 0 ] is

[ μ 0 ] = [ ε 0 ] [L] 2 [T] –2
[ μ 0 ] = [ ε 0 ] [L] –2 [T] +2
[ μ 0 ] = [ ε 0 ] –1 [L] 2 [T] –2
[ μ 0 ] = [ ε 0 ] –1 [L] –2 [T] 2

Correct answer: [ μ 0 ] = [ ε 0 ] –1 [L] –2 [T] 2

A particle of mass m is projected form the ground with an initial speed μ 0 at an angle α with the horizontal. At the highest point of its trajectory, it makes a completely inelastic collision with another identical particle, which was thrown vertically upward from the ground with the same initial speed u 0 . The angle that the composite system makes with the horizontal immediately after the collision is
