Assertion: An electron and proton enters a magnetic field with equal velocities, then, the force experienced by the proton will be more than electron.
The mass of proton is `1837` times more than electron.

Options

A. If both the assertion and reason are true and reason is a true explantion of the assertion.
B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.
C. If the assertion is true but reason false
D. If both the assertion and reason are false.

Explanation

To solve the question, we need to analyze the assertion and the reasoning provided.

### Step 1: Understand the Assertion
The assertion states that when an electron and a proton enter a magnetic field with equal velocities, the force experienced by the proton will be greater than that experienced by the electron.

### Step 2: Recall the Formula for Magnetic Force
The magnetic force \( F \) experienced by a charged particle moving in a magnetic field is given by the formula:
\[
