Identical point charges (\(q\) each), are placed at the eight corners of a cube of side \(a.\) When one of the charges is removed, the electric field at the center becomes \(E_c.\)
Now, identical point charges (same magnitude \(q\) each), are placed at the four corners of a square of side \(a.\) When one of the charges is removed, the electric field at the center becomes \(E_s.\) Then,
1. \(\frac{E_s}{2}=\frac{E_C}{3}\)
2. \(\frac{E_s}{3}=\frac{E_C}{2}\)
3. \(\frac{E_s}{\sqrt2}=\frac{E_C}{\sqrt3}\)
4. \(\frac{E_s}{\sqrt3}=\frac{E_C}{\sqrt2}\)
