Answer:
Explanation:
From the question we are told that
The number of turns is
The radius is
The position from the center consider is x = 3.45 cm = 0.0345 m
The induced emf is
Generally according to Gauss law
=>
Where A is the cross-sectional area of the solenoid which is mathematically represented as
=>
=> ggl;
Here is the permeability of free space with value
=>
=>
<u>Solu</u><u>tion</u><u> </u><u>:</u><u>-</u>
Given that ,
- Initial Velocity of car = 44km / hr.
- Final Velocity of car = 0km / hr.
- Acceleration = -5km/hr².
To Find :
- Time taken to stop the car .
So , here use first equⁿ of motion which is ,
where ,
- v is final Velocity.
- u is Initial velocity.
- a is acceleration.
- t is time taken.
Now , substituting the respective values ,
