Question 98)

Part 1)

A charged cloud system produces an electric field in the air near Earth's surface. A particle of charge -2.1 × 10^-9 C is acted on by a downward electrostatic force of 4.0 × 10^-6 N when placed in this field. (a) What is the magnitude of the electric field? (b) What is the magnitude of the electrostatic force on a proton placed in this field? (c) What is the gravitational force on the proton? (d) What is the ratio of the electrostatic force to the gravitational force in this case?

Part 2)

A block with a mass of 11.1 g and a charge of +6.70 × 10^-5 C is placed in an electric field with x component E_x = 2.77 × 10³ N/C, y component E_y = -728 N/C, and z component E_z = 0. (a) What is the magnitude of the electrostatic force on the block and (b) what angle does that force make with the positive x direction? If the block is released from rest at the origin at time t = 0, what are its (c) x and (d) y coordinates at t = 2.80 s?

Part 3)

An electron is shot at an initial speed of v₀ = 4.62 × 10⁶ m/s, at angle θ₀ = 40.9 ˚ from an x axis. It moves through a uniform electric field E→ = (5.40 N/C)j→. A screen for detecting electrons is positioned parallel to the y axis, at distance x = 1.84 m. What is the y component of the electron's velocity (sign included) when the electron hits the screen?

1. The magnitude of the electric field due to a small charged object is 12N/C at a distance of 6m from the charge. What is the field 3m away from the charge? 2. Two charged spheres, 3 cm apart, repel each other with a force of 2.4 x10^-8N. Determine the magnitude and sign of the charge on each, if one has twice the charge (of the same sign) as the other. 3. Calculate the electric field intensity midway between two...

When a charged particle moves in an electric field, the field performs work on the particle. Thus, the energy of the field decreases, turning into kinetic energy of the particle. Does the magnetic field of a permanent magnetic similarly lose energy and perform work when moving a conductor with a current?
