The measurements of two quantities along with the precision of their respective measuring instruments are given as:
$A = 2.5 \, m/s \pm 0.5 \, m/s$
$B = 0.10 \, s \pm 0.01 \, s$
The value of $AB$ will be:

Along the $X$-axis,three charges $\frac{q}{2}, -q$ and $\frac{q}{2}$ are placed at $x=0, x=a$ and $x=2a$ respectively. The resultant electric potential at $x=a+r$ (if $a \ll r$) is: ($\varepsilon_0$ is the permittivity of free space)
