Question #3 answer a,b, and c.
If a negative charge q where traveling in a direction v under a magnetic field B, and a magnetic force acting on it. (a) In which direction would the magnetic force act? (b) In which way would a positive charges flow for the following situation? (c) Suppose the current flow into the page and the magnetic field is to the right, then in which way does the magnetic force act for a negative charge? (4) Suppose two charges q_1 = 1.0 nC and q_2 = -2.0 nC are separated by a distance of 2.0 m. Find the electric potential of a point half-way between the two charges. q_1 = 1 times 10^-9 q_2 = -2 times 10^-9Explanation / Answer
(a) F = q(vxB)
F = -q(i x j)
F = - k
magnetic force along into the pase
(b) F = q(vXB)
+i = +q(v x j)
v = -k
positive charge is moving along into the page
(c) F = L(IxB)
F = L(-k x i)
F = -j
the magnetic force acts down for negative charge
