The effect of air resistance on projectile motion

In this post, we will find the effect of air resistance on projectile motion. We have seen that in the absence of air resistance, the trajectory or path followed by a projectile is a parabola and that the path depends only on the initial speed and angle of projection. But in the real world, all […]

Solution to problems – class 9 physics – Set 1 Q 60

Problem Statement 60) A metallic sphere of mass 2 kg and volume 2.5 x 10-4 m3 is completely immersed in water. Find the buoyant force exerted by water on the sphere. Density of water = 1000 kg/m3 Solution Volume of the water displaced = volume of the completely immersed sphere=2.5 x 10-4 m3 Mass of […]
