Torque = (force perpendicular to the radius) x (length of the radius)

Torque = (25 N) x (5 m)

<em>Torque = 125 N-m</em>

QveST [7]

Answer:

I_max= 1000 A

Explanation:

Expression of torque is given by

τ= BIA Sinθ

B= strength of magnetic field

I= current

A= Area

for maximum torque θ=90°⇒sin 90=1

Now for I_max= τ/BA

Let us take the average magnetic field of the earth as 50μT.

Area is calculated as

$A=\pi d^2/4=\pi\times0.16^2/4$

$A=0.02 m^2$

Substitute the values and calculate for maximum current

$I_{max}= \frac{\tau}{BA}$

$I_{max}= \frac{1\times10^{-3}{50\times10^{-6}\times0.02}$

I_max= 1000 A

HELP PLEASE<br>Can someone please explain to me why the answer would be 2.45m/s?

marissa [1.9K]

It's basically asking for the acceleration. When an object is in free fall, the acceleration is just gravity. so in this case ∆v = 2.45 because it is the gravity on that planet.
