Question

Problem 2: An imaginary particle π has mass m 5 x 10-27 kg and charge q +3c 4.8x 10-19 C. Compare the magnitude of the electric repulsion between two π particles with that of gravitational attraction between them. Problem 3: Two equal charges 22 x 10-6 C are located at -0, y 0.3 m and z 0, V0.3 m respectively. What are the magnitude and direction of the total electric force that q1 and g2 exert on a third charge qs 4.0 x 10-6 C located at z-0.4 m, y 0 m? Problem 4: What is the magnitude of the electric field É at a field point 2.0 m from a point charge q 4.0 x 109 C? Problem 5: When the terminals of a battery are connected to two parallel conducting plates with a small gap between them, the resulting charges on the plates produce a nearly uniform electric field E between the plates. Assume that positively charge plane is a lower one and negatively charged plane is an upper one, so the field E is pointing upward. The magnitude of the electric field is known to be = 1 x 104 N/C (a) If an electron (charge e1.6 x 109 C and mass m 9.1 x 10-31 kg) is released from the rest at the upper plate, what is its acceleration? (b) What speed and kinetic energy does it acquire while traveling 1.0 cm to the lower plate? Problem 6: Charge Q is uniformly distributed on a ring of radius R. Find an electric field at a point P on the ring symmetry axis at a distance a from its center
