Q1: The figure shows equipotential lines for a dipole formed by charges whose potentials are $+15\mathrm{V}$ and $?15\mathrm{V}$. Suppose you want to measure the potential difference between the points A and B with a voltmeter. Where would you place the positive and negative voltmeter leads? What value of the potential difference will the voltmeter read (both sign and magnitude)?
