Explanation:
From the question we are told that
The diameter of the ring is
The length of the solenoid is
The diameter of the solenoid is
The number of turns is N = 1500
The change in current in the solenoid is
The time taken is
Generally the radius of the ring is
=>
=>
Generally the area of the ring is mathematically represented as
=>
=>
Generally the induced emf is mathematically represented as
Here
Here is the permeability of free space with value
So
=>
So
=>
Answer:
a
The radial acceleration is
b
The horizontal Tension is
The vertical Tension is
Explanation:
The diagram illustrating this is shown on the first uploaded
From the question we are told that
The length of the string is
The mass of the bob is
The angle made by the string is
The centripetal force acting on the bob is mathematically represented as
Now From the diagram we see that this force is equivalent to
where T is the tension on the rope and v is the linear velocity
So
Now the downward normal force acting on the bob is mathematically represented as
So
=>
=>
The centripetal acceleration which the same as the radial acceleration of the bob is mathematically represented as
=>
substituting values
The horizontal component is mathematically represented as
substituting value
The vertical component of tension is
substituting value
The vector representation of the T in term is of the tension on the horizontal and the tension on the vertical is
substituting value
