Question

A circular ring of radius 'a' is charged uniformly and the charge per unit length is . The electric field at its centre is

​

Answer 1

Answer:

HEY

listen ring of radius r is uniformly charged per unit length of the electric field at the centre is zero because electric field jab ham log lete hain tab uska uski kyon and close charge ko ho gai hai

Answer 2

THE ELECTRIC FIELD AT THE CENTRE OF THE CIRCULAR RING IS 'ZERO'.

Explanation:

• The electric field is the field that is around charged point/particles, in return it applies field on the other particles.
• The electric potential at the center of the ring is same as due to a point charge.
• The electric field will be zero as the field due to one half of the ring will cancel out the field due to other half.
• Therefore, making the field equal to zero.
