Electric potential [XII] 1

               YASH  CLASSES

                    Electric potential  [XII]

 1. Two equal and opposite a charges 12μC are
     placed at a separation of 30 cm . calculate the
    dipole moment. Also find Electric potential at
    a point at distance 25 m from the dipole
   [1] on its end on position .
   [2] on its broad side on position .

 2. Two equal and opposite a charges 10μC are
     placed at a separation of 10 cm . calculate the
    dipole moment. Also find Electric potential at
    a point at distance 35 m from the dipole
   [1] on its end on position .
   [2] on its broad side on position .

 3. An electron situated at a distance 15 m on the
    axis of an Electric dipole of dipole moment
   21x 10-9 cm from its center is brought towards
    the dipole at  a  point  at  distance  12 m  from
    its center calculate the work done .

 4. An electron situated at a distance 10m on the
    axis of an Electric dipole of dipole moment
   14x 10-9cm from its center is brought towards
    the dipole at  a  point  at  distance  8 m  from
    its center calculate the work done .

 5.Two plates are kept at a separation of 50 cm
     with  potential difference of 25 V in them .
     Calculate  the  intensity  of  electric  field
     between  the  plates .
