The magnetic force on a point moving charge is `F=q(vxxB)`.
Here `q=` electric charge
`v=` velocity of the point charge
`B=` magnetic field
The dimensions of `B` is

Options

A. `[AMLT^(-1)]`
B. `[A^(-1)MLT^(-2)]`
C. `[A^(-1)MT^(-2)]`
D. none of these

Explanation

To find the dimensions of the magnetic field \( B \) from the given formula for the magnetic force on a point charge, we can follow these steps:

### Step 1: Write down the formula for magnetic force
The formula for the magnetic force \( F \) on a point charge is given by:
\[ F = q(v \times B) \]
where:
