Mathematically, Force \((F)\) is proportionate to Mass \((m)\) multiplied by Acceleration \((a)\); i.e. symbolically, \(F \propto m \times a\). If an object-Increases its acceleration by 10%, and loses 5% of its mass, by how much will the resultant force change?
Explanation: 10% বাড়লে acceleration \(a\) হয়ে যাবে, \(1.1a\)। 5% কমলে mass \(m\) হয়ে যাবে, \(0.95m\)। So, new force, \(1.1a \times 0.95m = 1.045ma\)। যা আগের force এর চেয়ে 4.5% বেশি।
