Question

if tides are caused by moons gravitational pull then if we put water in big n deep pan in a full moon night, will the water give tides

Answer 1

isn't our earth a big spherical pan in itself ?
so gravitational pull is nothing but attractive force between two or more bodies dependent on their masses.

TECHNICALITIES

F=G (m1)(m2)/R^2

m1 m2 masses

so the direction of force will be
towards the heavier body.

so if u have a very big pan size of a continent or something the moon will have a gravitational pull.
also think about this if there is a water sphere heavier than the moon itself it will attract the moon itself ;)

Answer 2

Yes, the tides are caused by moons gravitational pull. Because of eclipses.
