An object descends vertically at constant velocity in sea. The three forces acting on the object are viscous drag upthrust and weight. Which relationship between their magnitude is correct?

ایک شے سمندر میں مستقل رفتار پر عمودی طور پر اترتی ہے۔ آبجیکٹ پر کام کرنے والی تین قوتیں چپچپا ڈریگ اپرسٹ اور وزن ہیں۔ ان کی وسعت کے مابین کون سا تعلق درست ہے؟
Explanation
  • The object moves vertically downward at constant velocity, meaning forces are balanced.
  • Weight is greater than upthrust because an additional force (viscous drag) also acts upward to balance the system.
