A massless square loop ,of wire of resistance 10 ohm supporting a mass of 1 g , hangs vertically with one of its sides in a uniform magnetic field of 10 ^3 G , directed outward in the shaded region. A dc voltage V is applied to the loop . For what value of V , the magnitude force will exactly balance the weight of supporting mass of 1 g . ( if sides of the loop is 10 cm and g = 10 m /s^2 )
