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 .
