JEE MainPhysicsCapacitorMCQ+4 / −1
A parallel plate capacitor is made of two circular plates separated by a distance 5mm5mm5mm and with a dielectric of dielectric constant 2.22.22.2 between them. When the electric field in the dielectric is 3×104 V/m3 \times {10^4}\,V/m3×104V/m the charge density of the positive plate will be close to:
  1. A
    6×10−7  C/m26 \times {10^{ - 7}}\,\,C/{m^2}6×10−7C/m2
  2. B
    3×10−7  C/m23 \times {10^{ - 7}}\,\,C/{m^2}3×10−7C/m2
  3. C
    3×104  C/m23 \times {10^4}\,\,C/{m^2}3×104C/m2
