PHYS208 Fundamentals of Physics II

Hint for Ch. 23, 22P

You may reduce each of the 4 field contributions if you wish and then sum; HOWEVER, I would highly recommend that you make a sketch, consider the symmetry of the situation, and work out the resultant direction without numbers.

Definitely save substitution of the numerical values until the very last step!
