Answer:
The radius of the circular plate is 0.774 m
Explanation:
Given;
distance between the parallel plates, d = 1.53 cm = 0.0153 m
electric field energy density between plates, = 4.41 J/m³
Potential energy of the capacitor, = 0.127 J
Energy density is given as;
where;
V is volume
Volume is given as;
V = Ad
where;
A is area
A = V / d
A = (0.0288) / (0.0153)
A = 1.882 m²
Area of circular plate is given as;
A = πr²
where;
r is the radius of the circular plate
Therefore, the radius of the circular plate is 0.774 m
Answer:
Electric current produces a magnetic field. This magnetic field can be visualized as a pattern of circular field lines surrounding a wire. ... Magnetic Field Generated by Current: (a) Compasses placed near a long straight current-carrying wire indicate that field lines form circular loops centered on the wire.

Answer:
Explanation:
Let the length of the string is L.
Let T be the tension in the string.
Resolve the components of T.
As the charge q is in equilibrium.
T Sinθ = Fe ..... (1)
T Cosθ = mg .......(2)
Divide equation (1) by equation (2), we get
tan θ = Fe / mg
As θ is very small, so tanθ and Sinθ is equal to θ.
