a) a truck has much wider tyres why?
b) a child sitting along a swimming pool feels lighter while lowering his legs in water.why?
Dear Student
(a) Pressure = Force /Area
A truck has much wider tyre to reduce pressure on road/mud so that it not sink on a road or mud.
(b) child sitting along a swimming pool feels lighter while lowering his legs in water becuase water applies a buoyant force in upward direction which balance child weight.
