Acar travels northward at 75 km/h along a straight road in a region where the earth's magnetic field has a at a specified angle component of 0.50 x 10-4 t perpendicular to earth's surface directed upward. what is the emf induced between the left and right side of the car, separated by 1.7 m? a) e = 6.4 m v b) = 0 v c) e= 1.8 mv d) e = 3.6 mv

The emf induced between the left and right side of the car is 1.8 mV.

(c) is correct option

Explanation:

Given that,

Velocity of car =75 km/h

Magnetic field

Distance = 1.7 m

We need to calculate the induced emf

Using formula of emf

Where, B = magnetic field

v = velocity

l = length

Put the value into the formula

Hence, The emf induced between the left and right side of the car is 1.8 mV.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.
