You will now examine the relationship between the number of field lines through a surface and the angle between
(You will need a protractor to measure angles.)
1. Place the loop over the nails so that the number of field lines through k is a maximum. Determine the angle between
2. Rotate the loop until there is one fewer row of nails passing through it. Determine the angle between
3. On graph paper, plot a graph of nversus
(Let the number of field lines through the surface be a negative number for angles between

- Review. Two insulating spheres have radii r1 and r2, masses m1 and m2, and uniformly distributed charges q1 and q2. They are released from rest when their centers are separated by a distance d. (a) How fast is each moving when they collide? (b) What If? It the spheres were conductors, would their speeds be greater or less than those calculated in part (a)? Explain.arrow_forwardReview. Two insulating spheres have radii 0.300 cm and 0.500 cm, masses 0.100 kg and 0.700 kg, and uniformly distributed charges 2.00 C and 3.00 C. They are released from rest when their centers are separated by 1.00 m. (a) How fast will each be moving when they collide? (b) What If? If the spheres were conductors, would the speeds be greater or less than those calculated in part (a)? Explain.arrow_forwardTime left 0:26:2 Which of the following is true in the first part of the electric Field Mapping Experiment? O a. The galvanometer reads the potential difference between the pointer and the cathode. O b. If the reading of the galvanometer for a given position of the pointer and a given position of the sliding contact along the rheostat is zero, then if the sliding contact is moved the galvanometer will be different from zero. O . The galvanometer measures the electric field between the anode and the cathode. O d. The galvanometer is used to find points between the two electrodes that have the same potential as the cathode. O e. If the sliding contact along the rheostat is kept at the same position there is only one position of the pointer between the two electrodes for which the galvanometer reads zero.

- An electron is projected with an initial speed v0 = 1.40x106 m/s into the uniform field between the parallel plates in (Figure 1). Assume that the field between the plates is uniform and directed vertically downward, and that the field outside the plates is zero. The electron enters the field at a point midway between the plates.
