A particle moving with velocity v → = i ^ + 3 j ^ produces an electric field E → = 2 k ^ at some point. It will produce a magnetic field at that point, which is equal to

Options

  1. A6 i ^ - 2 j ^ c 2
  2. B6 i ^ + 2 j ^ c 2
  3. Czero
  4. Ddata insufficient

Correct answer

A. 6 i ^ - 2 j ^ c 2

Step-by-step solution

B → = μ 0 4 π q v → × r → r 3 ⇒ E → = 1 4 π ε 0 q r → r 3 B → = μ 0 ε 0 v → × E → = v → × E → c 2 B → = 6 i ^ - 2 j ^ c 2
