Answer:
The maximum electric field
Explanation:
From the question we are told that
The diameter is
The magnetic field of the cylinder is
The frequency is
The radial distance is
This magnetic field can be represented mathematically as
The initial magnetic field is the average between the variation of the magnetic field which is represented as
Then is the amplitude of the resultant field is mathematically evaluated as
The electric field induced can be represented mathematically as
At maximum electric field
Answer:
10 million joules or 10,000 KJ
Explanation:
Work= Force x Displacement
convert 5km into meters -5km=5000m
W= 2000N x 5000m
w=10,000,000 Joules
or 10,000KJ
Answer:
a)
b)
c)
Explanation:
Given that
Length =L
Mass = m
Force on elemental part
dF= dm ω² r
dm = m/L dr
dF= ω² r m/L dr
By integrating from r to L
Velocity V
Answer:
Induced emf will be 0.468 volt
Explanation:
We have given diameter of wire d = 15.3 cm
So radius
So area
Change in magnetic field dB = 0.26 - 0.77 = -0.51 T
Time for change in magnetic field dt = 0.26 sec
We know that emf is given by
