10. How much current is required to produce a force of 0.96 N on a 75 cm long wire oriented at right angles to a 0.24 T magnetic field?

A. 0.050 A

B. 0.17 A

C. 5.3 A

D. 0.19 A

5.3 A (<--- (0.96)/((75.0e-2)*(0.24)) )

correct

To calculate the current required to produce a force of 0.96 N on a 75 cm long wire oriented at right angles to a 0.24 T magnetic field, you can use the formula:

Force (F) = current (I) * length of the wire (L) * magnetic field (B)

Rearranging the formula to solve for current (I), we get:

I = F / (L * B)

Plugging in the given values:

I = 0.96 N / (75 cm * 0.24 T)

Converting the length of the wire to meters:

I = 0.96 N / (0.75 m * 0.24 T)

Simplifying the calculation:

I = 0.96 N / (0.18 T)

I ≈ 5.33 A

Therefore, the current required to produce a force of 0.96 N on a 75 cm long wire oriented at right angles to a 0.24 T magnetic field is approximately 5.33 A.

So the correct answer is C. 5.3 A.

To determine the amount of current required to produce a force on a wire in a magnetic field, you can use the equation:

F = I * L * B

Where:
F is the force in Newtons
I is the current in Amperes
L is the length of the wire in meters
B is the magnetic field strength in Tesla

In this case, we are given:
F = 0.96 N
L = 75 cm = 75 * 0.01 m = 0.75 m
B = 0.24 T

Using the formula, we can rearrange it to solve for I:
I = F / (L * B)

Now, let's substitute the values:

I = 0.96 N / (0.75 m * 0.24 T)
I = 5.3 A

Therefore, the amount of current required to produce a force of 0.96 N on a 75 cm long wire oriented at right angles to a 0.24 T magnetic field is 5.3 Amperes.

So the correct answer is C. 5.3 A.
