A light string passing over a smooth light fixed pulley connects two blocks of masses m₁ and m₂. If the acceleration of the system is g/8, then the ratio of the masses is:
A uniform magnetic field of 2 × 10⁻³ T acts along positive Y-direction. A rectangular loop of sides 20 cm and 10 cm with current of 5 A is in the Y–Z plane. The current is in the anticlockwise sense with reference to the negative X axis. Magnitude and direction of the torque is:
