The value of mass m so that the system (a parallel plate capacitor) will remain at equilibrium.

Question

The value of mass m so that the system (a parallel plate capacitor) will remain at equilibrium. (A) Zero (B) (σ2A/εog) (C) (σ2A/4 εog) (D) (σ2A/2 εog)

Tardigrade Admin · Accepted Answer

mg = T ...(i) T = [(σ/2ϵo)] (σ A)...(ii) ⇒ m =(σ2 A/2ϵo g )

Q. The value of mass m so that the system (a parallel plate capacitor) will remain at equilibrium.

Zero

$\frac{σ ^{2} A}{ε _{o} g}$

$\frac{σ ^{2} A}{4 ε _{o} g}$

$\frac{σ ^{2} A}{2 ε _{o} g}$

$m g = T ... (i)$
$T = [\frac{σ}{2 ϵ _{o}}] (σ A) ... (ii)$
$\Rightarrow m = \frac{σ ^{2} A}{2 ϵ _{o} g}$

Zero

εo​gσ2A​

4εo​gσ2A​

2εo​gσ2A​

mg=T...(i) T=[2ϵo​σ​](σA)...(ii) ⇒m=2ϵo​gσ2A​

$\frac{σ ^{2} A}{ε _{o} g}$

$\frac{σ ^{2} A}{4 ε _{o} g}$

$\frac{σ ^{2} A}{2 ε _{o} g}$

$m g = T ... (i)$
