An airplane in the earth’s magnetic field can develop a voltage between its wingtips.

Svetradugi [14.3K]

Answer:

$emf=0.125\ V$

According to the Fleming's Left left hand rule we have higher potential on the right edge of the wing.

Explanation:

Given:

velocity of plane, $v=250\ m.s^{-1}$

magnetic field, $B=5\times 10^{-5}\ T$

angle between velocity and magnetic field, $\theta=30^{\circ}$

span of the wing, $l=20\ m$

We know:

$emf=B.l.v\ sin\theta$

$emf=5\times 10^{-5}\times 20\times 250\times sin30^{\circ}$

$emf=0.125\ V$

According to the Fleming's Left left hand rule we have higher potential on the right edge of the wing.

A rope is wrapped around a pulley many times. The pulley can be modeled as a solid disk of radius R and mass M, and a mass mA ha

The magnitude of the tangential acceleration of the hanging mass is 2mg/MR

<h3>Tangential acceleration of the hanging mass</h3>

The tangential acceleration of the hanging mass around the pulley is determined from the principle of conservation of angular momentum as shown below;

τ = Iα

Where;

I is the moment of inertia
α is the angular velocity

$\alpha = \frac{\tau}{I} \\\\\alpha = \frac{mgR}{3/2MR^2} \\\\\alpha = \frac{2mgR}{3MR^2} \\\\\alpha = \frac{2mg}{3MR}$

Where;

m is the hanging mass
M is the mass of solid disk

The tangential acceleration is calculated as follows;

$a = \alpha R\\\\a = \frac{2mg}{3MR} \times R\\\\a = \frac{2mg}{3M}$

Thus, the magnitude of the tangential acceleration of the hanging mass is 2mg/MR
