Three capacitors of capacitances \(2\) pF, \(3\) pF, and \(4\) pF are connected in parallel. The charge on the \(4\) pF capacitor, if the combination is connected to a \(100\) V supply, is:
1. \(4\times10^{-10}\) C
2. \(3\times10^{-9}\) C
3. \(2\times10^{-10}\) C
4. \(1\times10^{-9}\) C

The equivalent capacitance of the circuit is:

  
1. \(200\) pF
2. \(\frac{200}{3}\) pF
3. \(200\) \(\mu\)F
4. \(150\) pF$$
