Vertical displacement of a plank with a ...

Vertical displacement of a plank with a body of mass `'m'` on it is varying according to law `y=sin omegat +sqrt(3) cos omegat`. The minium value of `omega` for which the mass just breaks off the plank and the moment it occurs first arter `t=0` are given by: `(y "is positive vertically upwards")`

A

`sqrt((g)/(2)),(sqrt2)/(6)(pi)/(sqrtg)`

B

`(g)/(sqrt2),(2)/(3)sqrt((pi)/(g))`

C

`sqrt((g)/(2)),(pi)/(3)sqrt((2)/(g))`
