Two equipotential surfaces have a potential of -10V and 90V respective...
Potential = high potential - low potential
so our high potential is 90V and low potential is 10V,
potential = 90-(-10)=100V
so our high potential is 90V and low potential is 10V,
potential = 90-(-10)=100V

Explanation:
The difference in potential between two equipotential surfaces is given by the potential difference between them. Therefore, the potential difference between the two surfaces is:
Potential difference = potential of higher potential surface - potential of lower potential surface
= 90 V - (-10 V) = 100 V
Hence, the correct answer is option (D).
Summary:
The difference in potential between two equipotential surfaces is the potential difference between them. In this case, the potential difference is 100 V, which is the difference between the potentials of the two surfaces (-10 V and 90 V).
The difference in potential between two equipotential surfaces is given by the potential difference between them. Therefore, the potential difference between the two surfaces is:
Potential difference = potential of higher potential surface - potential of lower potential surface
= 90 V - (-10 V) = 100 V
Hence, the correct answer is option (D).
