Where k is the spring constant in N/m and x is displacement from equilibrium position in m. Evaluating:
A/ The potential energy is stored in the spring is 44.1 J.
Answer:
B(max) = 3.7971 × T
Explanation:
given data
radius R = 26 mm
plate separation d = 4.0 mm
potential difference Vm = 220 V
frequency f = 76 Hz
V = (220 V) sin[2π(76 Hz)t]
solution
we know that E will be
E = V ÷ d ............1
put here value
E =
and here we take as given r = R
so A = π R² .................2
and
ФE = E × A
ФE = .....................3
so use use here now Ampere's Law that is
∫ B ds = .....................4
and
here is = 0 and r = R
so
.....................5
and put here value we get
B = .....................6
put here value for B maximum cos(2πft) = 1
and we get B (max)
B(max) = ....................7
put here all value
B(max) =
solve it we get
B(max) = 3.7971 × T
