Q1. A rectangle measuring 30.0 {rm cm} by 40.0 {rm cm} is located inside a region of a spatially uniform magnetic field of 1.30 T, with the field perpendicular to the plane of the coil. The coil is pulled out at a steady rate of 2.00 {rm{ cm/s}} travelling perpendicular to the field lines. The region of the field ends abruptly as shown.

Find out the emf induced in this coil when it is all inside the field.

Q2. Calculate the magnitude of the linear momentum for the following cases.

A proton with mass 1.67 x 10-27 kg, moving with a speed of 5.65 x 10^6 m/s
