The battery that runs the potentiometer should have voltage of 8V

The battery of potentiometer can have a voltage of 15 V and R adjusted so that the potential drop across the wire slightly exceeds 10 V

The first portion of 50 cm of wire itself should have a potential drop of 10 V

Potentiometer is usually used for comparing resistances and not voltages

shall increase along the positive x-axis

shall decrease along the positive x-axis

shall point along the negative x-axis

shall increase but the direction changes because of the intersection of Q with q₂ and q₃
