1. The problem statement, all variables and given/known data A 20cm wire carrying a current of 10A is placed in a uniform magnetic field of 0.3T. If the wire makes an angle of 40 degrees with the direction of magnetic field, find the force acting on the wire. 2. Relevant equations F=LIB sin<theta> 3. The attempt at a solution I got the answer:: 0.35, but in the textbook, the answer written at the back is 0.39....which one's correct??
