The capacitance of an isolated charged sphere is independent of both the <u>charge </u>on the sphere and the<u> potential difference</u>, it is dependent only on its <u>radius</u>
The capacitance of an isolated sphere is calculated as follows;
- let the charge on the sphere = Q
- let the potential difference = V
- let the radius of the sphere = R
The potential difference is given as;
where;
k is Coulomb's constant
The capacitance is given as;
From the equation above, the capacitance (c) is directly proportional to its radius (R) and independent of both the charge (Q) on the sphere and the potential difference (V).
Thus, the capacitance of an isolated charged sphere is independent of both the <u>charge </u>on the sphere and the<u> potential difference</u>, it is dependent only on its <u>radius</u>

Probable how long they were moving
Answer:
Place the convex lens on a 'V' stand. . ii) Light a candle and take it far away from the lens along the principal axis. iii) Adjust the screen on the other side of the lens to get a clear image on it. iv) Measure the distance between the 'V' stand and the screen which gives a rough idea of the focal length of the lens.
Answer:
The correct answer would be C. 5.0kg
Explanation:
The mass of an object never changes unless parts of the object are taken away. In other words, although the gravitational force is different on the moon then on the earth the mass of the object would remain the same.
