Problem

Three point charges are fixed in the

xy

-plane as follows: •

q_1 = +3\,\mu\text{C}

at the origin

(0,0)

, •

q_2 = -4\,\mu\text{C}

(0,\,0.12\,\text{m})

on the positive

y

-axis, •

q_3 = +5\,\mu\text{C}

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

on the positive

x

-axis. A test charge

q_0 = +2\,\mu\text{C}

is placed at

(0.12\,\text{m},\,0.12\,\text{m})

. (a) Determine the

x

-component of the net electrostatic force on

q_0

. (b) Determine the

y

-component of the net electrostatic force on

q_0

. (c) Hence find the magnitude of the net force acting on

q_0
