SSC CGL 5 August, 2017 Shift 1 Question 1(Reasoning) with Solution.

1. In the following question, select the related word pair from the given alternative:
Power: Watt::?:?.
Options:
A. Pressure : Newton
B. Force : Pascal
C. Resistance : Mho
D. Work : Joule.


Answer: D.

SI Unit of work is Joule.

SI Unit of Pressure is pascal.

Pressure is defined as force per unit area.

P(Pressure) = F / A or Force / Area.

1 Pascal = 1 Newton / meter square

SI Unit of Force is Newton.

Force(F) = Mass(M) * Acceleration(A)
1 Newton = KG Meter / second 

SI Unit of Resistance is Ohm.

Mho is SI unit of electrical conductance
