Question: 4 a 200 c charged 100 g cork ball is...

Question details

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 balls 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. The initial diameter quickly pulled taut, and the kink shrinks to f the kinkc is magnitude igure 4 the average voltage induced between endadiameter ofis 2.00cmde of 25.0 mT nk is undisturbed, but the magnetic field increases to a diameter of zero in 50.0 ms. Determine pulled a induced between endpoints 4 and B. Include the polarity. (b) mT in 4.00 the ki average voltage across terminals A and B, including to 100 polarity, during this period.

2. In Figure 3, the cube is 40.0 cm on each edge. Four straight segments of wire-ab, bc, cd, and da-form a closed loop that carries a current 1 -5.00 A in the direction shown. A uniform magnetic field of magnitude B-0.0200T is in the positive y-direction. Determine the magnitude and direction of the magnetic force on each segment. (10) Figure3
