A uniform magnetic field `vecB` of magnitude 0.2 T exists in the plane of paper from left to right. A conducting wire, bent in an irregular manner, and carrying a current `i` , equal to 5A is placed in the plane of paper as shown in figure. Force acting on the wire (in Newton) is

Answer

2

Explanation

Magnetic force acting on curved will be same as that on straight wire joining the ends of curved wire and carrying the same current. `F_("mag")=iLB sin 90^(@)=5xx2xx0.2=2N`
