One newton of force is defined as the force that gives a body of mass 1 kg an acceleration of
A9.8 m s⁻²
B1 cm s⁻²
C1 m s⁻²
D10 m s⁻²
Answer & Solution
Correct answer: C. 1 m s⁻²
1. By F = ma, 1 N produces an acceleration in a 1 kg mass.
2. Setting F = 1 N and m = 1 kg gives a = 1 m s⁻².
3. Hence 1 N = 1 kg m s⁻².
4. Rule out 1 cm s⁻²: that defines the dyne, the CGS unit of force.
