4. A 2.00 C charged 1.00 g cork ball is suspended vertically on a 0.500 m long light string in the presence of a uniform downward-directed electric field of magnitude E-1.00x105 N/C. If the ball is displaced slightly from the vertical, it oscillates like a simple pendulum. (a) Determine the period of the ball's oscillation. (b) Should gravity be included in the calculation for part (a)? Explain. (15) 3. The magnetic field shown in Figure 4 directed into the paper....

Please answe all on of the current induced in the resistor at the instant 3. In Figure 2, what is the direction the switch is closed? current in ε' s Figure 2 clock were running slow, how could we adjust the length of the If a grandfather pendulum to correct the time? 4.
In the following figure, determine the direction of the current in resistor ab: A) As switch S is closed. B) As coil B is moved away from coil A with the switch closed; C) As the resistance of R is increased while the switch remains closed A circular loop of wire with radius R, is in a region of spatially uniform magnet field as shown below. The magnetic field is directed into the plane of the figure. Calculate the direction...
