Complete question:
A 200 g load attached to a horizontal spring moves in simple harmonic motion with a period of 0.410 s. The total mechanical energy of the spring–load system is 2.00 J. Find
(a) the force constant of the spring and (b) the amplitude of the motion.
Answer:
(a) the force constant of the spring = 47 N/m
(b) the amplitude of the motion = 0.292 m
Explanation:
Given;
mass of the spring, m = 200g = 0.2 kg
period of oscillation, T = 0.410 s
total mechanical energy of the spring, E = 2 J
The angular speed is calculated as follows;
(a) the force constant of the spring
(b) the amplitude of the motion
E = ¹/₂kA²
2E = kA²
A² = 2E/k
Answer:
Part a)
Part B)
Part C)
Explanation:
Part a)
Magnetic field due to a long ideal solenoid is given by
n = number of turns per unit length
now we know that magnetic field due to solenoid is
Now magnetic flux due to this magnetic field is given by
Part B)
Now for mutual inductance we know that
now we have
Part C)
As we know that induced EMF is given as
