7. Two parallel horizontal conductors are suspended by light vertical threads each of length 75cm. Each conductor has a mass of 40gm per m. When no current flows through them, they are 0.5 cm apart. When same current flows through each coductor the separation is 1.5 cm. The value and direction of current is 1) 14 A in same direction 2) 14 A in opposite direction 3) 196 A in same direction 4) 196 A in opposite direction ICICIMADVANCONI

Two parallel horizontal conducting wires are suspended by light vertical threads of length 75 cm. Each conductor has a mass of 40 g per metre, and when there is no current they are 0.5 cm apart. Equal current in the wires results in a separation of 1.5 cm. Find the value of current in the conductors.
