Answer:
B = 1.3734*10^-7 T
Explanation:
I'm going to take a shot at this since I doubt anyone else would, but I might be wrong, so keep that in mind. Okay, with that out of the way, we know the equation for capacitance:
We also know that it is put in series with a resistor. Since it is initially uncharged and is in series with a battery, it is step response. Using KVL, we will get:
We also know from Ampere's law, there is a magnetic field because of the current induced (right hand rule). From this we can calculate the magnetic field using a contour integral. We can simplify and avoid using Biot-Savart law by using the path of integration of a circle, thus:
Okay now we got all that out of the way, lets first find the area of the plates so we can use the first equation to get capacitance.
Now we need to calculate the current through the capacitor. To do this, use the step response to calculate the voltage drop across the capacitor and then use KVL calculate the current through the resistor. So:
Finally Ampere's law:
B = 1.3734*10^-7 T

The value is
Explanation:
From the question we are told that
The mass of the block is
The initial speed of the block before entering the rough section is
The time taken is t = 0.5 s
The speed with which the block leaves the rough section is
Generally from kinematic equation
=>
=>
=>
Generally the magnitude of the average frictional force is mathematically represented as
=>
=>
The negative sign show that the force is acting in the opposite direction to the direction of motion of the block
