The capacitance between the points A and B in the following figure.

The electric field in a region of space is given as $$\mathbf{E}=\left(5 \mathrm{NC}^{-1}\right) x \hat{i}$$. Consider point $$A$$ on the $$Y$$-axis at $$y=5 \mathrm{~m}$$ and point $$B$$ on the $$X$$-axis at $$x=2 \mathrm{~m}$$. If the potentials at points $$A$$ and $$B$$ are $$V_A$$ and $$V_B$$ respectively, then $$\left(V_B-V_A\right)$$ is

In the given circuit values of $$I_1, I_2, I_3$$ are respectively

The resistance of wire at $$0^{\circ} \mathrm{C}$$ is $$20 \Omega$$. If the temperature coefficient of the resistance is $$5 \times 10^{-3}{ }^{\circ} \mathrm{C}^{-1}$$. The temperature at which the resistance will be double of that at $$0^{\circ} \mathrm{C}$$ is
