A charge Qa = 4 X 10^-9 C experiences a et electrostatic force of 1.2 X10^-6 N toward the north.
a. Find the electric field (magnitude and direction) at the location of Qa.
b. If the charge Qa is replaced by a charge Qb = -1.5 X10^-9 C, what force (magnitude and direction) will Qb experience?
Homework Answers
a) Electric Field E= F/Q =
1.2*10-6/(4*10-9) =300 N/c along north
b) Electric Force experienced by Qb =
(1.2*10-6)*(1.5*10-9)/(4*10-9)
=4.5*10-7 N towards South
Electric Field E= F/Q =
4.5*10-6/(1.5*10-9) =300N/c along north
