Question

A charge q (> 0) moves towards the centre of a circular loop of radius R along its axis. The magnitude of B along the periphery of the loop is ______.

विकल्प

• zero

• `mu_0/(4pi)"qvR"/(sqrt(("R"^2+x^2)^3))`

• `"qvR"/(sqrt("R"^2+x^2))`

• None of these

Answer 1

A charge q (> 0) moves towards the centre of a circular loop of radius R along its axis. The magnitude of B along the periphery of the loop is `underlinebb(mu_0/(4pi)"qvR"/(sqrt(("R"^2+x^2)^3)))`.
