Point charges each equal to +q are placed at vertices of an equilatera...
Explanation:

Given:
- Three point charges each equal to +q are placed at vertices of an equilateral triangle of side 'l'.
- Net charge 'q' is placed at the circumcentre of the triangle.

Explanation:

Electric Field Due to a Point Charge:
- The electric field due to a point charge q at a distance r is given by E = k * q / r^2, where k = 1/(4πε₀).

Electric Field at the Circumcentre:
- The net electric field at the circumcentre due to the three charges is the vector sum of the electric fields due to each individual charge.
- Since the charges are equidistant from the circumcentre, the magnitudes of the electric fields due to each charge are the same.
- The net electric field at the circumcentre is zero because the electric fields due to the charges cancel out each other.

Net Charge at the Circumcentre:
- The net charge at the circumcentre is equal to the sum of the three charges placed at the vertices of the equilateral triangle.
- Therefore, the net charge q' at the circumcentre is 3q.

Final Answer:
- Therefore, the net charge 'q' placed at the circumcentre of the triangle is (C) zero.
