A wire of mass 100 g is carrying a current of 2A towards increasing x in the form of y=x^2(-2mlexle+2m). This wire is plasced in a magnetic field B=-0.02hatk tesla. The ascceleration of the wire ("in"m/s^2) is |

Answer» `-1.6hatj`  MEGNETIC foerce on POQ=magnetic force on straight wire PQ having the CURRENT. Hence, `F=i(IxxB)i(PQxxB)` `=2[(4i)XX(-0.02hatk)]` `=(0.16hatj)` `:. A=F/m=((0.16hatj))/0.1=(1.6hatj)m/s^2` |
