A conductor in electrostatic equilibrium contains a cavity in which there are two point charges: q1= 6 uC and q2= -10 uC. The conductor itself carries a net charge -2 uC. How much charge is on the inner and outer surface of the conductor? Please show all work, 5 stars will be awarded to best answer with all work and reasoning shown.
Homework Answers
inside the condutor charge is
Q = 6 - 10
Q = -4 uC
The inner side of condutor will have charge equal and oposite to the charge present inside the cavity
so that there is zero field inside the conductor
Qin = -(-4)
Qin = 4 uC
charge on inner surface is 4 uC
Now , as charge on conductor is fixed
Qin + Qout = -2 uC
Qout + 4 = -2
Qout = -6 uC
Charge on the outer surface is -6 uC
