Vedclass · Answer

(C) In forced oscillations of a mechanical system,the equation of motion is $m(d^2x/dt^2) + b(dx/dt) + kx = F(t)$.In an $LCR$ series circuit,the equation for charge $q$ is $L(d^2q/dt^2) + R(dq/dt) + (1/C)q = V(t)$.Comparing these two equations:$1$. Mass $m$ corresponds to Inductance $L$.$2$. Damping constant $b$ corresponds to Resistance $R$.$3$. Spring constant $k$ corresponds to the reciprocal of capacitance $1/C$.$4$. Displacement $x$ corresponds to charge $q$.Therefore,the physical quantity corresponding to the spring constant $k$ is $1/C$.

Give the name of the physical quantity in an $LCR$ circuit that corresponds to the spring constant $k$ in forced oscillations.
