What will be the effect of increasing or decreasing the voltage of cell on the null point in a meter bridge?

It would not have any change.
The meter bridge works on the principal of wheatstone bridge, i.e the null point depends if the bridge is balanced by equal proportion of resistances on both sides, not the emf of battery used.
