Homework Statement
A current I9 = 2 A flows through the 9 ohm resistor. At what rate does the battery deliver energy to the entire circuit?
Homework Equations
There are 3 resistors in the circuit, all wired in parallel. r1=15 ohms, r2=12 ohms, r3=9 ohms

Homework Statement
A negative charge Q1 = -8 nC is fixed on the x-axis at (x = -4, y = 0). A positive charge Q2 = +8 nC is fixed on the x-axis at (x = 4, y = 0). For the sake of reference, consider point A, at (x = 0, y = 5). All locations are in meters.
What is the sign of the...
Follow up questions:
What is the potential at x = -5 ?
How much work is required to move the +4 nC charge (Q2) from its original location at x = 5 to x = 3 ?
Any explanation would help?
Thank You
Homework Statement
A pair of charges sits on the x-axis, a charge Q1 = +9 nC at the origin and Q2 = +4 nC at x = 5. Assume no other charges are present. All coordinates are in meters.
At which one of these points is the net electric field equal to zero?
