NDA GK Questions with Answers

Q1142.General ScienceAsked in: CDS · CDS-I 2018, GKMedium

A wire of copper having length l and area of cross-section A is taken and a current I is flown through it. The power dissipated in the wire is P. If we take an aluminium wire having same dimensions and pass the same current through it, the power dissipated will be

  1. A.P
  2. B.< P
  3. C.> P
  4. D.2P
Show answer
Correct answer: C. > P

The power turned into heat in a wire carrying a current I is P = I²R, and the resistance of a wire is R = ρl/A, where ρ is the resistivity of its material.

Q1160.General ScienceAsked in: NDA · NDA-I 2023, GATHard

One block of 2.0 kg mass is placed on top of another block of 3.0 kg mass. The coefficient of static friction between the two blocks is 0.2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s², the maximum value of the frictional force is :

  1. A.50 N
  2. B.30 N
  3. C.4 N
  4. D.10 N
Show answer
Correct answer: C. 4 N

The friction between the blocks is the only force that drags the top block along, and its largest possible value is μ times the normal force from the top block.
