Problem

A point charge

-6\,\mu\text{C}

produces an electric field of magnitude

2.4\times10^5\,\text{N}\,\text{C}^{-1}

at a point

P

that is

5.0\,\text{cm}

away. (i) What will be the magnitude of the electric field at a point

Q

that lies

15\,\text{cm}

from the charge along the same line? (ii) State whether the directions of the fields at

P

and

Q

are the same or opposite.
