The magnetic field in a region is given by `vecB =B_(0)((x)/(a))^hatk`. A square loop of side d is placed with its edges along the x and y axes. The loop is moved with a constant velocity `vecv=v_(0)hati` The emf induced in the loop is :

A

`(B_(o)v_(o)d^(2))/(a)`

B

`(B_(o)v_(o)d^(2))/(2a)`

C

`(B_(o)v_(o)d)/(2a)`
