Consider the force \( \mathrm{F} \) on a charge ' \( \mathrm{q} \) ' due to a uniformly charged spherical shell of radius \( \mathrm{R} \) carrying charge \( \mathrm{Q} \)
P distributed uniformly over it. Which one of the
W following statements is true for \( F \), if ' \( q \) ' is placed at distance \( r \) from the centre of the shell ?
[JEE Main-2020 (September)]
(1) \( \mathrm{F}=\frac{1}{4 \pi \varepsilon_{0}} \frac{\mathrm{Qq}}{\mathrm{r}^{2}} \) for all \( \mathrm{r} \)
(2) \( \frac{1}{4 \pi \varepsilon_{0}} \frac{\mathrm{Qq}}{\mathrm{R}^{2}}\mathrm{F}0 \) For \( \mathrm{r}\mathrm{R} \)
(3) \( \mathrm{F}=\frac{1}{4 \pi \varepsilon_{0}} \frac{\mathrm{Qq}}{\mathrm{r}^{2}} \) for \( \mathrm{r}\mathrm{R} \)
(4) \( \mathrm{F}=\frac{1}{4 \pi \varepsilon_{0} \mathrm{R}^{2}} \) for \( \mathrm{r}\mathrm{R} \)
