An equilateral prism of mass \(m\) rests on a rough horizontal surface with coefficient of friction \(\mu\). A horizontal force \(F\) is applied on the prism as shown. If the coefficient of friction is sufficiently high so that the prism does not slide before toppling, then the minimum force required to topple the prism is:
For the circuit shown, the current is to be measured. The ammeter shown is a galvanometer with resistance \(R_g = 60.00\,\Omega\) converted into an ammeter by a shunt resistance \(R_s = 0.02\,\Omega\). The value of the current is:
