# Can somebody determine the point between these charges where the electric field force equals to zero? Thank you!

Two charges of respectively +10,0µC and +40,0µC are within 50 centimeters from each other. --> electric field force = 0 ?

Clearly both the charges try to push a test charge in opposite direction.

So,we can write,

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
