A pendulum is first vibrated on the surface of earth. Its period is T. It is then taken to the surface of moon where acceleration due to gravity is 1/6th of that on earth. Its period will be :

Answer»

`(T)/(6)`
`(T)/(3)`
`(T)/(sqrt(3))`
`Tsqrt(6)`

SOLUTION :`(T_(2))/(T_(1))=sqrt((a_(1))/(a_(2)))`
`:. T_(2)=T sqrt((g)/(g//6))=T sqrt(6)`
Thus CORRECT choice is (d).
