The p.d across a parallel-plate capacitor is 103V. If the distance between the two plates is 10cm. Calculate the magnitude of the electric field strength between the plates.
1.0 x 104Vm-1
1.0 x 105Vm-1
1.5 x 105Vm-1
2.0 x 105Vm-1
解释
E = \(\frac{v}{d} = \frac{10^3}{0.1}\)
= 10000
= 1.0 x 104Vm-1
= 10000
= 1.0 x 104Vm-1
