    4000k-ohm to 10,000k-ohm

    Explanation:

    As we know that time constant for an RC circuit is t=RC

    Putting the values of t we can get the range of varaiable resistor as;

    t=RC

    Putting t=2 we get the first value of the range for the variable resistor

    2=R*0.500*10^-6

    R=2 / (0.500*10^-6)

    R=4*10^6

    R=4000k-ohm

    Now putting t=5 we get the final value for the range of variable resistor

    t=RC

    5=R*0.500*10^-6

    R=5 / (0.500*10^-6)

    R=10*10^6

    R=10,000k-ohm

    So variable resistance must be made to vary in the range from 4000k-ohm to 10,000k-ohm
