+2.0\,\mu\text{C}

point charge experiences an electric force of magnitude

F

when it is located

0.40\,\text{m}

from a

-6.0\,\mu\text{C}

point charge. Which of the following single changes would most nearly quadruple the magnitude of that force? (a) Reducing the separation to

0.10\,\text{m}

while keeping both charges the same (b) Reducing the separation to

0.20\,\text{m}

while keeping both charges the same (c) Doubling the magnitude of the

+2.0\,\mu\text{C}

charge only (d) Doubling the magnitudes of both charges while increasing the separation to

0.80\,\text{m}
