Find equivalent capacitance between points A and B. Assume each conducting plate has same dimensions and neglect the thickness of plate. It is given that \[ \frac{6A\varepsilon_0}{d}=7\,\mu F, \] where A is the area of plates.

When an electric heater is switched on, the current \(i\) is plotted against time \(t\). Taking into account the variation of resistance with temperature, which of the following best represents the resulting curve?

A proton accelerated by a potential difference $V=500\,\text{kV}$ moves through a transverse magnetic field $B=0.51\,\text{T}$ as shown in the figure. The width of the magnetic field region is $d=10\,\text{cm}$. Then the angle $\theta$ through which the proton deviates from the initial direction of its motion is (approximately)
