A parallel plate condenser has a capacity C. The space between the plates is half filled by oil of dielectric constant k as shown in the figure. The ratio of new capacity to the original capacity is :
- k : 1
- (1 + k) : 1
- \(\frac{1+\mathrm{k}}{2}: 1\)
- \((1+k): \frac{1}{2}\)
Answer
(C) 1+ k 2 : 1
