The electric field in a particular thundercloud is N/C. What is the magnitude of the acceleration of an electron in this field, given that the charge of an electron is C and the mass of an electron is kg?
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 of charge C experiences an upward force of magnitude N when it is placed in a particular point in an electric field.
What is the electric field magnitude at that point?
If a charge is placed there, what is the magnitude of the force on it?
An electron has an initial velocity of m/s in a uniform -N/C electric field. The field accelerates the electron in the direction opposite to its initial velocity.
The charge of an electron is C.
How long does it take the electron to come to rest?
What is the electron’s velocity when it returns to its starting point?
What is the electric field at a point where the force on a C charge is N/C?
