Question

Two positively charged particles each having charge Q and are d distance apart. A third charge is introduced in midway on the line joining the two. Find nature and magnitude of third charge, so that the system is in equilibrium ______.

विकल्प

• q = `(-"Q")/4`

• q = `"Q"/4`

• q = `(3"Q")/4`

• q = `-(3"Q")/4`

Answer 1

Two positively charged particles each having charge Q and are d distance apart. A third charge is introduced in midway on the line joining the two. Find nature and magnitude of third charge, so that the system is in equilibrium `underlinebb("q"=(-"Q")/4)`.
