Problem

Two point charges are placed in the

xy

-plane as follows: Charge

q_1 = +5\,\mu\text{C}

is fixed at the origin

(0,0)

and charge

q_2 = -3\,\mu\text{C}

is fixed at the point

(0,\,0.30\,\text{m})

. A point

P

is located at

(0.40\,\text{m},\,0)

. (i) Calculate the magnitude of the electric field at

P

due to

q_1

. (ii) Calculate the magnitude of the electric field at

P

due to

q_2

. (iii) Determine the magnitude and direction of the net electric field at

P

produced by the two charges.
