Question

The electrical field from two charges in the plane of the paper is represented by the dashed lines and arrows below.

Select from these responses (North, South, East, West, Greater Than, Equal to, Less than, True/False) for the answers to the following:

a) The magnitude of the E-field at R is ... than at M.

b) The force on a (+) Test charge at N is directed ...

c) The force on a (-) test charge at N is directed ...

d) The sign of the charge on the right is positive ...

e) The magnitude of the carge on the left is ... that on the right.

f) The force on a (-) test charge at P is directed...

g) The force on a (-) test charge at k is zero.

Explanation / Answer

(a) Greater than (greater the line density, greater will be field strength)

(b) force will be along the field lines

- South

(c) for negative charge, opposite of line direction.

-North

(d) negative charge

(e) on left charge there are 13 lines

on right charge -> 18 lines

- less than

(f) to the left

(g) False
