Q.3 What base quantities are involved in these derived physical quantities; force, pressure, power and charge.
(a) Force: Force F = ma SI Unit of force is Newton (N) = kgms-2 Base quantities involved in force a mass, length, and time. (b) Pressure: Pressure = force/area Pressure = F/A The SI unit of force (F = ma) is Newton N = kgms and unit of area A is m² = kgm … Read more
