In a collinear collision, a particle with an initial speed v0 strikes a stationary particle of the same mass. If the final total kinetic energy is 50% greater than the original kinetic energy, the magnitude of the relative velocity between the two particles, after collision, is :

Options

A. ` I/L`
B. `l^(2)/L`
C. `L/1`
D. ` L^(2)/l`

Answer

2

Explanation

Magnetic field produced by a current in a large square loop of wire at its center
`B(2sqrt2mu_(0)i)/(piL)`
The magnetic flux phi12 that links big loop with the small square loop of side` l (I<thereforeThe mutual inductance` _(12), = phi_(12)= 2sqrt2mu_(0)i)/(pi(l^(2)/(L)`
`M_(12)prop (l^(2) /L)`
