A thin metallic spherical shell contains a charge Q on its surface. A point charge q1 is placed at the center of the shell, and another charge q2 is placed outside the shell. All three charges are positive. Then the force on charge q1 is:-

Question

A thin metallic spherical shell contains a charge Q on its surface. A point charge q1 is placed at the center of the shell, and another charge q2 is placed outside the shell. All three charges are positive. Then the force on charge q1 is:- <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/p-qpesjhd5b0iz0l0x.jpg" /> (A) towards right (B) towards left (C) zero (D) none of these

We know that the electric field inside the metallic cavity due to the charge present on the surface is zero and this phenomenon is known as electrostatic shielding.
So, the force experienced by charge

q_{1}

is also zero.

Q. A thin metallic spherical shell contains a charge Q on its surface. A point charge q1​ is placed at the center of the shell, and another charge q2​ is placed outside the shell. All three charges are positive. Then the force on charge q1​ is:-

towards right

towards left

zero

none of these

We know that the electric field inside the metallic cavity due to the charge present on the surface is zero and this phenomenon is known as electrostatic shielding. So, the force experienced by charge q1​ is also zero.

Q. A thin metallic spherical shell contains a charge $Q$ on its surface. A point charge $q_{1}$ is placed at the center of the shell, and another charge $q_{2}$ is placed outside the shell. All three charges are positive. Then the force on charge $q_{1}$ is:-

We know that the electric field inside the metallic cavity due to the charge present on the surface is zero and this phenomenon is known as electrostatic shielding.
So, the force experienced by charge $q_{1}$ is also zero.
