In a certain 0.1 m^(3) of space, electric potential is found to be 5 V throughout. What is the electric field in this region ?

A square loop of side 12 cm with its sides parallel to X and Y axes is moved with a velocity of 8 cm s^(-1) in the positive x-direction in an environment containing a magnetic field in the positive z-direction. The field is neither uniform in space nor constant in time. It has a gradient of 10^(-3) T cm^(-1) along the negative x-direction (that is it increases by 10^(-3) T cm^(-1 ) as one moves in the negative x-direction), and it is decreasing in time at the rate of 10^(-3) T s^(-1) . Determine the direction and magnitude of the induced current in the loop if its resistance is 4.50 mOmega .
