An electric dipole consisting of charge $-q$ and $+q$ is placed in a uniform electric field $\vec{E}$ such that its dipole moment $\vec{p}$ makes an angle $\theta$ with the direction of $\vec{E}$. The net force $\vec{F}$ and torque $\tau$ acting on the dipole are (a) $\vec{F}=0,\ \tau=0$ (b) $\vec{F}\neq0,\ \tau\neq0$ (c) $\vec{F}=0,\ \tau\neq0$ (d) $\vec{F}\neq0,\ \tau=0$

> > [!TLDR] > The two equal-and-opposite forces on a dipole's charges always cancel in a uniform field, but their lines of action generally differ, producing a net torque un …
