Physics · Electric Charges and Fields

हिन्दी

Consider the following statements regarding electric charge:\n Statement I: At the macroscopic scale, the quantisation of electric charge has no practical significance and charge can be treated as continuous.\n Statement II: A typical macroscopic charge of \( 1\,\mu\text{C} \) contains an enormous number of elementary charges (around \( 10^{13} \) times \( e \)), making the discrete grainy nature of charge unnoticeable.\nWhich of the following options is correct?

  1. A
    Both Statement I and Statement II are correct
  2. B
    Both Statement I and Statement II are incorrect
  3. C
    Statement I is correct but Statement II is incorrect
  4. D
    Statement I is incorrect but Statement II is correct
View Answer & Solution

Correct answer · Option A

Both Statement I and Statement II are correct

Explanation

At macroscopic levels, charge magnitudes involve huge multiples of \( e \) (\( 1\,\mu\text{C} \approx 10^{13}e \)), making charge steps indiscernible and rendering charge effectively continuous. Thus both statements are correct.
