Asked by Bobby
PLEASE HELP!! I HAVE A TEST TOMORROW!!
i just posted this problem but a very important drawing was left out!
if Q=30 uC, q=5.0 uC, and d=30cm, what is the magnitude of the electrostatic force on q in N?
(Ke= 8.99 x 10^9 Nm^2/C^2)
(uC= micro coulombs)
(u= 10^-6)
d 2d
O<--->O<--------->O
Q q 2Q
a. 15
b. 23
c. zero
d. 7.5
e 38
i know coulomb's law but i don't know how to apply it to this problem
