Question

7. Two identical point charges are placed on the x-axis separated by a distance "d". The magninade of the force F1
SON OON
If the distance is doubled the magnitude of the new force F is
b. 1ON
C. 20N
d. 25N

Expert Solution

Step 1

F = KQ₁Q₂/d²

Force is inversely proportional to d²

So if the distance is doubled then Force will become one fourth

F₂₁_new = KQ1Q₂ /(2d)² = 5/4 = 1.25 N

Step by step
