Discuss
Answer & Solution
Answer: Option C
Solution:
Here's an explanation of the problem and solution:

The question deals with the electric field intensity due to a point charge.

The electric field intensity (E) due to a point charge (Q) at a distance (r) is given by the formula: E = kQ/r2, where k is a constant.

This means the electric field intensity is inversely proportional to the square of the distance.

So, if the distance is halved, the electric field intensity will be quadrupled (multiplied by 4).

Initially, at 4 meters, the electric field intensity is 200 N/C.

When the distance is reduced to 2 meters (which is half of 4 meters), the new electric field intensity will be 200 N/C * 4 = 800 N/C.

Therefore, the correct answer is Option C: 800 N/C
