The axis of a ring shaped 100-turns coil is parallel to z-axis, as shown in the figure. In each of the turns a current I= 0.1 A flows and the area of the coil is 0.5m2. A homogeneous magnetic field B-(i- 2j + 4k) T passes through the whole area of the ring. What is the net torque on the coil in units of N.m? O -4j - 2k O 10i + 5j O -8i + 2j O 2i+j 8i + 4j
