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
Find the surface tension force on water inside a tube and height to which the water rises in the tube.

A 2.47 kg steel ball strikes a massive wall at 11.7 m/s at an angle of alpha = 67.2° with the plane of the wall. It bounces off with the same speed and angle. If the ball is in contact with the wall for 0.218 s, what is the magnitude of average force..
A 1600 kg car starts from rest at A, coasts 180m through a dip and comes to stop at B after coasting a distance d on level ground. If the rolling resistance is a constant force of 280N, conclude the distance d.
In a game of basketball, a forward makes a bounce pass to the center. The ball is thrown with an initial speed of 2.50 m/s at an angle of 15.5° above the horizontal. It is released 0.73 m above the floor. What horizontal distance does the ball cover ..

An automobile club plans to race a 780 kg car at the local racetrack. The car needs to be able to travel around several 170 m radius curves at 85 km/h. What must the banking angle of the curves be so that the force of the pavement on the tires of the..
A 27 pound meteorite struck the car, leaving a dent 24 cm deep in the trunk. If the meteorite struck the car with a speed of 440 m/s, what was the magnitude of its deceleration, assuming it to be constant.
