A Levels Physics (9702)•9702/13/M/J/19
Question 37 from 9702/13/M/J/19

Explanation

Not enough information to solve

Steps:

  • Identify the potential divider formula: V_out = V_in × (R / (R_total)), where R_total is the sum of resistors.
  • No values for V_in, V_out, or other resistors are given in the problem.
  • Without voltage ratios or total resistance, R cannot be calculated.
  • Additional circuit details are required to proceed.

Why B is correct:

  • Cannot verify without data; stated as correct but uncomputable here.

Why the others are wrong:

  • A: No basis to rule out without specifics.
  • C: No basis to rule out without specifics.
  • D: No basis to rule out without specifics.

Final answer: Not enough information.
