Microcoulomb means ( 10^-6 ) Coulomb.

1. Consider the following three point charges arranged along the x-axis: a. q, has a charge of -7.0 uC and is located at x = -3.0 m b. q, carries a charge of 3.0 uC and is located at the origin c. q; has a charge of -7.0 uC and is located at x = 3.0 m WI -+ : ..-11 forco summerienred by - ? -3.0 m 3.0 m + 9, = -7.0 HC 92 = +3.0 HC (3 =-7.0 HC
