EXERTED by a fluid that opposes the weight of a partially or fully IMMERSED object.buoyancy force = weight of displaced fluidBuoyancy force = density of fluid × VOLUME of submerged body × acceleration DUE to gravityBuoyancy force = \({\rm{\rho VG}}\)Buoyancy force = \({\rm{\rho lhbg}}\)Fig: Partially submerged bodyIf body is displaced upward 'h' decrease, hence Buoyancy force decrease.If body is displaced in horizontal direction, then h remain same hence Buoyancy force and its location remain same.
