A potentiometer wire PQ of 1 m length is
connected to a standard cell E1. Another cell E2
of emf 1.02 V is connected with a resistance ‘r’
and switch S (as shown in figure). With switch
S open, the null position is obtained at a
distance of 49 cm from Q. The potential
gradient in the potentiometer wire is :

Let S be the sum of the first 9 terms of the
series :
{x + k\(a\)} + {x2 + (k + 2)\(a\)} + {x3 + (k + 4)\(a\)}
+ {x4 + (k + 6)\(a\)} + .... where a \(\ne\) 0 and x \(\ne\) 1.
If S = \({{{x^{10}} - x + 45a\left( {x - 1} \right)} \over {x - 1}}\), then k is equal to :
{x + k\(a\)} + {x2 + (k + 2)\(a\)} + {x3 + (k + 4)\(a\)}
