Two identical charges particle each carrying charge $q = 0.1 m C$ and of mass $m = 10 g m$ are project along two parallel lines separated by a distance $l$ with equal speed $V_{0} = 10^{4} m / s$ in opposite directions. In the beginning electrostatic interaction between the charges can be ignored due to a large distance between them. The minimum distance between the particles is found to be $12 c m$ . The value of $l$ is equal to

Question

Two identical charges particle each carrying charge

q = 0.1 m C

and of mass

m = 10 g m

are project along two parallel lines separated by a distance

l

with equal speed

V_{0} = 10^{4} m / s

in opposite directions. In the beginning electrostatic interaction between the charges can be ignored due to a large distance between them. The minimum distance between the particles is found to be

12 c m

. The value of

l

is equal to
