At the distance of \( 5 \mathrm{~cm} \) and \( 10 \mathrm{~cm} \) from surface of a uniformly
\( \mathrm{P} \) charged solid sphere, the potentials are \( 100 \mathrm{~V} \) and \( 75 \mathrm{~V} \) respectively. Then which of the following statements is/are
W correct about the given situation :
(A) Potential at its surface is \( 150 \mathrm{~V} \)
(B) The charge on the sphere is \( \frac{50}{3} \times 10^{-10} \mathrm{C} \)
(C) The electric field on the surface is \( 1500 \mathrm{~V} / \mathrm{m} \)
(D) The electric potential at its centre is \( 250 \mathrm{~V} \)
