A body of mass 2 kg is moving with an acceleration of 5 m/s². The rate of change of its momentum is:
A. 10 kg m/s
B. 2.5 N
C. 10 N
D. 0.4 N
Answer: Option C
Solution (By JKSSB Mock Tests)
According to Newton's Second Law of Motion, the rate of change of momentum is directly proportional to the applied unbalanced force. Rate of change of momentum = Force = mass × acceleration. Force = 2 kg × 5 m/s² = 10 Newtons (N). Note that '10 kg m/s' is a unit of momentum, not its rate of change.
Explanation:
Newton's law of gravitation: F ∝ 1/r². If distance r becomes r/2, new force F' ∝ 1/(r/2)² = 4/r² = 4F. So force quadruples. This inverse square law is fundamental for gravitational, electric, magnetic forces.
Explanation:
Lactometer is a type of hydrometer used to check purity of milk by measuring specific gravity. Adulteration with water lowers density. It doesn't measure temperature or viscosity directly.
Explanation:
Steel has high retentivity, retains magnetism, used for permanent magnets. Soft iron has low retentivity, used for electromagnet core (temporary). Alnico, ferrites also used.
