Consider the statement given below and choose the correct option.
Assertion: Water strider slides easily on the surface of the water.
Reason: Water strider experiences less buoyant force.
Assertion (A): The buoyant force on a submerged rigid object can be considered to be acting at the center of mass of the object.
Reason (R): In rigid body, force distributed uniformly through its volume can be considered to be acting at the centre of mass of the body.
