Current I flows through solenoid of length L having N number of turns, when it is connected to DC emf. If charged particle is projected along the axis of solenoid with a speed `v_(0)`, them find the force on the charged particle in the solenoid.

Explanation

To find the force on a charged particle projected along the axis of a solenoid carrying a current, we can follow these steps:

### Step 1: Understand the Magnetic Field Inside the Solenoid
A solenoid produces a uniform magnetic field inside it when a current flows through it. The magnetic field \( B \) inside a long solenoid can be given by the formula:
\[ B = \mu_0 \frac{N}{L} I \]
where:
