प्रश्न
A hemisphere is uniformly charged positively. The electric field at a point on a diameter away from the centre is directed ______.
विकल्प
perpendicular to the diameter
parallel to the diameter
at an angle tilted towards the diameter
at an angle tilted away from the diameter
उत्तर
A hemisphere is uniformly charged positively. The electric field at a point on a diameter away from the centre is directed perpendicular to the diameter.
Explanation:
In case of a uniformly positive charged hemisphere, if a point is situated at a point on a diameter away from the centre, the electric field should be perpendicular to the diameter. In this case, the component of electric field intensity parallels the diameter cancel out.
