In a Hall effect experiment, a p-type semiconductor sample

In a Hall effect experiment, a p-type semiconductor sample with hole concentration p₁ is used. The measured value of the Hall voltage is V_H1. If the p-type sample is now replaced by another p-type sample with hole concentration p₂ where p₂ = 2p₁. What is the net Hall voltage V_H2?

We know that hall voltage is inversely proportional to the concentration i.e.,

V_H	1
	Concentration

Therefore,		V_H1	=	P₂
		V_H2		P₁

Therefore,		V_H1	=	P₂
		V_H2		P₁

or V_H2=		P₁	x V_H1 =	1	V_H1
		V_H2		2

Hence alternative (C) is the correct choice.
