Two metal plates have potential difference of 300V are 0.01m apart. Then the electric field between the plates is
3×102Vm−1
3Vm−1
3×104Vm−1
3×10−4Vm−1
E=300V0.01m=3×104 Vm−1
Two parallel metal plates are 3 mm apart and have a uniform electric field strength 500 Vm−1 between them. The potential difference between the plates is:
Two parallel plates are 0.03m apart. The electric field intensity between them is 3000 newton per coulomb. Calculate the potential difference between the plates?
