 A $3.00\U{N}$ metal bar, $1.50\U{m}$ long and having a resistance of
 $10.0\U{\Ohm}$, rests horizontally on conducting wires connecting it
 to the circuit shown in Fig.~27.62.  The bar is in a uniform,
-horizontal, $1.60\U{T}$ magnnetic field and is not attached to the
+horizontal, $1.60\U{T}$ magnetic field and is not attached to the
 wires in the circuit.  What is the acceleration of the bar just after
 the switch $S$ is closed?
