### Alternating Current Circuit

Q- Calculate the voltages V1 and V2 for the circuit shown in figure.

Solution:

### Rotational Motion

Q- A solid ball with mass M and radius R is rolling without slipping on a flat surface at 10 m/s. It then gets a small slope and rolls down 2 m from the top. Find the velocity of the ball after it passes the slope.

Solution:

### Photoelectric Effect

Q- The measurements of a photoelectric-effect experiment are graphed in in Figure, in which the intervals along the horizontal and vertical axes are respectively given by 5.9*1014 Hz and 2.50 V, respectively.

(a) What is the work function of the cathode?

(b) What experimental value of Planck's con…

### Rotation: Torque

Q- A block of weight 150 lb is placed on a rough horizontal surface and a horizontal force P = 60 lb is acting on it as in figure. The friction is sufficient to prevent sliding. Find the horizontal distance between the line of action of the weight of the block and the normal reaction of the surface.

### Kirchhoff's Law

Q- Find the mesh currents and voltage Vab for given network.

Solution:
