<h2>Hello!</h2>
The answer is:
The first option, the force tending to lift Rover is equal to 14.5 N.
<h2>Why?</h2>To calculate the force that is tending to lift Rover vertically, we need to calculate the vertical component force.
Since we know that the angle between the force and the ground is 29°, we can calculate the vertical component of the force using the following formula:
We are given that the force is equal to 30.0 N, so, calculating we have:
Also, we can calculate the horizontal component of the force using the following formula:
Hence, we have that the correct option is the first option, the force tending to lift Rover is equal to 14.5 N.
Have a nice day!

Answer:
Torque,
Explanation:
Given that,
The loop is positioned at an angle of 30 degrees.
Current in the loop, I = 0.5 A
The magnitude of the magnetic field is 0.300 T, B = 0.3 T
We need to find the net torque about the vertical axis of the current loop due to the interaction of the current with the magnetic field. We know that the torque is given by :
Let us assume that,
is the angle between normal and the magnetic field,
Torque is given by :
So, the net torque about the vertical axis is . Hence, this is the required solution.
