The distance between charges 
and 
is 0.2 m. The distance at which a third charge should be placed in order that it will not experience any force along the line joining the two charges is
Text Solution
Verified by ExpertsThe correct answer is:
C
If two opposite charges are separated by a certain distance, then for it’s equilibrium a third charge should be kept outside and near the charge which is smaller in magnitude.
Here, suppose third charge q is placed at a distance x from – 2.7 × × 10 –11 C then for it’s equilibrium |F 1 | = |F 2 |
⇒ ⇒ 
⇒ ⇒ x = 0.556 m
