I don't understand why calculus is necessary here . My intuition was that since electric force is a conservative force we could just take into account ya but in their solution they used calculus , could you please explain why thoroughoughly I'm having trouble visualizing what's going on I don't understand why calculus is necessary here .

Explanation / Answer

So basically your question is that why we use calculus method to solve this questions.

As you know that we can use calculus method to calculate the total change by integrating the small part of it within a proper limit.

We know

E = KQ / R²

Here if you observe in the above diagram, that is keep on changing, we need to calculate the net effect of electric field And electric field is inversely depend on electric field.

So, we need to calculate it within proper limit.
