Masses m, 2m, 3m, 4m,………,12m are kept on...

Masses `m`,` 2m`, `3m`, `4m`,………,`12m` are kept on the peripheri of a clock having a circular dial. The masses are kept such that `m` is kept at `1`, `2`, `3m` at `3`………`12m` at `12` . `vec g` is the gravitational field intensity at the centre of dial.

A

At `9 : 30` the hour hand is in the direction of `vecg`

B

At `3 : 30` the hour hand is in the direction of `vecg`

C

there will be no component of `vecg` along hour hand at `6 : 30`

D

There will be no component of `vecg` along hour hand at `12 : 30`
