Figure shows a solid sphere positioned just below the surface of a fluid and held there. Let the density of the fluid be sigma, force applied by fluid on the upper half of the sphere be F_(1) and the force on lower half be F_(2) (excluding the contribution due to atmospheric pressure). Pick correct option (s): |
