`q_1`, `q_2`, and `q_3`, are three point charges located in free space. Draw the vector diagram representing individual forces and total force on `q_1`

q_1 , q_2 , and q_3 , are three point charges located in free space. Calculate total force F_1 , on q_1

q_1 , q_2 , and q_3 , are three point charges located in free space. br What is the force between q_1 , and q_2 , if q_3 , is absent?

q_1 , q_2 , and q_3 , are three point charges located in free space. br What is the force between q_1 , and q_2 , if q_3 , is, present?

A metallic shell.has a point charge ‘q‘ kept inside its cavity. Represent its electric lines of forces?

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 the three charges are positive. Then the force on charge q, is
