Question

Two point charges, Q1 = -5.3 C andQ2 = 2.2 C , are located between two oppositely charged parallel plates, as shown in (Figure 1) . The two charges are separated by a distance ofx = 0.42 m . Assume that the electric field produced by the charged plates is uniform and equal toE = 60000 N/C . Neglect the charge redistribution in plates.

Calculate the magnitude of the net electrostatic force on Q1.

Calculate the magnitude of the net electrostatic force on Q1.

Explanation / Answer

Q1 = -5.3C and

Q2 = 2.2C

K = 9*10

E = 60000 N/C

|F| = 5.3*(10)*[{9*(10)*2.2*(10)*(1/0.42²... - (60000)]
|F| = 5.3*(10)*[112244 - 60000] = 0.2768932 Nor 0.28N
Direction is towards Q2.
