Electricity

Dry air will break down and generate a spark if the electric field exceeds about 2.95 x 10^6 N/C. How much charge could be packed onto a green pea (diameter 0.830cm) before the pea spontaneously discharges?

Electricity

What is the electric field at a point midway between a -7.67 micro coulombs and a +4.69 micro coulombs charge 3.65 cm apart? take the direction towards positive charge to be positive

Electrostatics: Electric Field

Calculate the magnitude of the electric field at one corner of a square 1.32 m on a side if the other three corners are occupied by 2.80 x 10^-6 C charges.

Electricity

What is the electric force ( with direction) on an electron in a uniform electric field of strength 2780 N/C that points due east? take the positive direction to be east.

magintude of net force

Three positive particles of charges Q = 61.8 micro coulombs are located at the corners of an equilateral triangle of side L = 16.3cm. Calculate the magnitude of the net force on each particle.
