Question
Two positive charges, each with Q = +13 µC, arefixed to the x-axis at x = +a andx = -a, where a = 4 m.
(a) Find the electric potential at point A on they-axis where (xA,yA) = (0, b) and b = 6 m.Take the zero of potential to be at infinity.
V(A) = V
-7e-6 NO
(b) A particle with charge q = -7 µC and massm = 2.2 x 10-4 kg is released from rest atpoint A. Find its speed at the origin.
v(O) = m/s
286.36 NO
(c) Can the particle escape to infinity?
Answer 1 for yes or 0 for no: *
0 OK
Explanation / Answer
Q = +13 µC, a = 4 m, b = 6m.
