`10^(12)alpha`- particles (Nuclei of helium) per second falls on a neutral sphere, calculate time in which sphere gets charged by `2mu C`.

Explanation

To solve the problem, we need to calculate the time it takes for a neutral sphere to accumulate a charge of \(2 \, \mu C\) when \(10^{12}\) alpha particles are falling on it per second.

### Step-by-Step Solution:

1. **Understanding Alpha Particles**:
- An alpha particle is the nucleus of a helium atom, which consists of 2 protons and 2 neutrons.
- The charge of an alpha particle is \(2 \times e\), where \(e\) is the charge of a proton.
