STD 12 - 2. Electric potential and capacitance — NEET STD 11 Science — Question

Gujarat BoardEnglish MediumSTD 11 ScienceNEETSTD 12 - 2. Electric potential and capacitance4 Marks
Question
The electric field $\vec E$ between two points is constant in both magnitude and direction. Consider a path of length d at an angle $\theta = 60^o$ with respect to field lines shown in figure. The potential difference between points $1$ and $2$ is
✓

Answer

Points $2$ and $3$ are equipotential points. Hence, potential difference between points $1$ and $2$ is the same as that between $1$ and $3$.

                  $\therefore V = Ed \,cos \,60^o$
