A mass ‘M’ is suspended from a ceiling through a string of length ‘L’. This mass moves in a circle of horizontal radius ‘r’ at constant speed such that it is a conical pendulum. The tension in the string will be
1
\(\frac{{mgL}}{{\left( {2\sqrt {{L^3} - {r^2}} } \right)}}\)
2
\(\frac{{mgL}}{{\sqrt {{L^2}} }}\)
3
\(mgL\sqrt {{r^2}} \)
4
\(\frac{{mgL}}{{\sqrt {{L^2} - {r^2}} }}\)
