Question

Match the Column I with Column II

	Column I (Physical quantity)		Column II (Name of unit)
(A)	Conductance	(p)	gray
(B)	Magnetic induction	(q)	lumen
(C)	Absorbed dose	(r)	tesla
(D)	Luminous flux	(s)	siemens

• A. A - s, B - r, C - p, D - q.
• B. A - p, B - q, C - r, D - s.
• C. A - q, B - p, C - s, D - r.
• D. A - r, B - s, C - p, D - q.

Answer 1

The correct option is A A - s, B - r, C - p, D - q.

1) Conductance (G) is reciprocal of resistance (R).

$\therefore G=\frac{1}{R}$

$\therefore G=\frac{I}{V}$ $[\therefore \text{since}R=\frac{V}{I}]$

And its Unit is Siemens (S)

2) When an emf [electromotive force] is induced in a circuit due to change in the magnetic flux associated with the circuit is called Magnetic Induction.

$B=\frac{F}{qv\sin \theta }$

Unit is Tesla

3) Absorbed Dose (D) is the amount of energy abdorbed per unit mass of tissue.

Unit is GRAY (Gy)

4) Luminous flux is the measurement of brightness of a light source in terms of energy emitted.

SI unit is Lumen.
