A wire along the x-axis carries a current of `3.50A` in the negative direction. Calculate the force (expressed in term of unit vectors) on a `1.00cm` sectioin of the wire exerted by these magnetic fiels.
a. `B=-(0.65T)hatj b. `B=+(0.56T)hatk c. `B=-(0.31T)hatj`
d. `B=_(0.33T)hati-(0.28t)hatk` e. `B=+(0.74T)hatj-0(0.36T)hatk`

Explanation

To solve the problem of calculating the force on a wire carrying a current in the presence of a magnetic field, we can follow these steps:

### Step-by-Step Solution

1. **Identify the Given Values:**
- Current, \( I = 3.50 \, \text{A} \) (in the negative x-direction)
- Length of the wire section, \( L = 1.00 \, \text{cm} = 0.01 \, \text{m} \)
- Direction of the current: \( -\hat{i} \)
