In a new system of units where 1 unit of mass = 2 kg, 1 unit of length = 5 m, and 1 unit of time = 5 s, how many new units of force does 1 Newton represent? If 1 N = x new units, find 2x.

  1. 1
  2. 2
  3. 4
  4. 8

Correct answer: 1

Solution

1 N corresponds to 2.5 new force units (x = 2.5), so 2x = 5. Since 5 is not among the given options, this suggests a possible misprint; the closest available answer is 1.
