A long straight wire carries a certain current and produces a magnetic field 2 ×10−4 Wb m−2 at a perpendicular distance of 5 cm from the wire. A particle say 'c' having charge equal to that of an electron is situated at 5 cm from the wire moves with a velocity of 107 m/s towards the wire perpendicularly. The magnitude of force experienced by the particle will be (charge of an electron =−1.6×10−19 C )
