The \(v-t\) graph of a moving object is given in figure. The maximum acceleration is
In a potentiometer the null point is received at 7th wire. If now we have to change the null point at \(9\text{th}\) wire, what should we do?
Five equal resistances each of resistance \(R\) are connected as shown in the figure. A battery of \(V\) volts is connected between \(A\) and \(B\). The current flowing in \(AFCEB\) will be
