The electric field strength in a particular thundercloud is N/C. What is the magnitude of the acceleration of an electron in this field?
A spherical water droplet of radius 25 μm carries an excess 250 electrons. What magnitude of vertical electric field is needed to balance the gravitational force on the droplet at the surface of the earth?
A particle with a charge of C is acted on by a force of magnitude N when it is placed in a particular point in an electric field.
What is the electric field magnitude at the point?
If a particle with a charge of C is instead placed at the point, what force acts on the particle?
