Auniform rectangular coil of total mass 270 g and dimensions 0.500 m * 1.00 m is oriented with its plane parallel to a uniform 4.00-t magnetic field (fig. e27.43). a current of 2.70 a is suddenly started in the coil. (a) about which axis (a1 or a2) will the coil begin to rotate? why? (b) find the initial angular acceleration of the coil just after the current is started.
