A uniform magnetic field vecB=0.25hatkT ...

A uniform magnetic field `vecB=0.25hatkT` exists in a circular region of radius `R=5m`. A loop of radius `R=5m` lying in `x-y` plane encloses the magnetic field at `t=0` and then pulled at uniform velocity `vecv=4hatim//s`. Find the emf induced (in volts) is the loop at `t=2` sec
