Question

When charges qa, qb, and qc are placed respectively at the corners a, b, and c of a right triangle, the potential at the midpoint of the hypotenuse is 20 V. When the charge qa is removed, the potential at the midpoint becomes 15 V. When, instead, the charge qb is removed (qa and qc both in place), the potential at the midpoint becomes 12 V. What is the potential at the midpoint if only the charge qc is removed from the array of charges?

    Answer:

    8v

    Explanation:

    First we apply super position principle

    Vt= v1 + v2+ v3

    Remove qa

    But vt= 20v

    So V = v2+v3

    V1= 20-15

    = 5v

    Remove qb

    V= v1+v3

    V=8v

    So the potential when qa and qc are remove is the potential due to qb

    Which is 8v
