QUESTION #0 Electric Force and Tension
A thin metallic wire having a cross-sectional area of 10⁻⁴ m² is used to make a ring of radius 30 cm. A positive charge of 2 nC is uniformly distributed over the ring, while another positive charge of 30 pC is kept at the centre of the ring. The tension in the ring is ______ N; provided that the ring does not get deformed (neglect the influence of gravity). {{IMG1}}
