1.Calculate the magnitude of the electric field at one corner of a square 1.43 m on a side if the other three corners are occupied by 2.80E-6 C charges

2.Three positive particles of charges Q = 74.1 μC are located at the corners of an equilateral triangle of side L = 15.7 cm, as seen in the figure below. Calculate the magnitude of the net force on each particle.

3.An electron (mass m = 9.11E-31 kg) is accelerated in the uniform field E (E = 1.78E+4 N/C) between two parallel charged plates. The separation of the plates is 1.40 cm. The electron is accelerated from rest near the negative plate and passes through a tiny hole in the positive plate, as seen in the figure below. With what speed does it leave the hole?Show that the gravitational force can be ignored by calculating the ratio of the gravitational to the electric force. Calculate that ratio.
