In a new system of units, unit of mass is 5 kg, unit of length is 2 m and unit of time is 10 sec. Value
of 5 N in new system of unit is;
30
40
50
60
1 N = 1 kg × (m / sec²)
1 N = 1 kg m / sec²
⇒ 5 N = 5 kg m / sec²
⇒ (2 × 5 N) / (10 × 10) = (5 kg × 2 m) / (10 sec × 10 sec)
⇒ 1/10 N = 5 kg (2 m) / (10 sec × 10 sec)
⇒ 1/10 N = 1 unit
⇒ 1 N = 10 unit
⇒ 5 N = 5 × 10 = 50 unit
∴ The correct answer is option (3).
