A bob of mass $\mathrm{m}=4\mathrm{kg}$is suspended from a massless string of length $l$. Other end of the string is fixed from the ceiling. A horizontal force $\mathrm{F}=\frac{3}{4}\mathrm{mg}$is applied on the bob when bob it at rest at the lowest position. Find maximum tension (in newton) in the string during the motion.

(Take $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$)
