Question

1. An electric field has an electric field strength 6000. N/C at a distance of 1.5 m. What is the strength of the field at a distance of 6.0 m?

2. 24. An alpha (α) particle is positioned in an electric field such that the gravitational force acting on it is equal to the electrostatic force.

             (q_α = 3.2 x 10^–19 C and m_α = 6.64 x 10^–27 kg)

a) What is the direction of the electric field at this point?

b) What is strength of the electric field?

c) If the field is located 0.25 m away, what is the magnitude of the charge?

3. Determine the potential at a point 0.50 m from a 20. µC point charge.

4. An electric field is parallel to the x-axis. What is the magnitude and direction of the electric field if the potential difference between x = 1.0 m and x = 2.5 m is found to be +900 V?

5. A charged droplet of mass 5.88 x 10^–10 kg is hovering motionless between two parallel plates. The parallel plates create have a potential difference of 24000 V and are 2.00 mm apart. What is the charge on the particle?
