The force on the rod will be equal to the weight of the rod to make the tension twice of its magnitude.
Now, m.g = B.i.l
here, m= mass of the rod= 10g = 0.01 kg
g = gravitational acceleration= 9.8 m/s²
B = magnetic field= 3 T
i = current in the rod
l = length of the rod= 5 cm = 0.05 m
Now, 0.01×9.8 = 3×i ×0.05
=> i = 0.65 Amp (approx)
The current will flow from left to right.
The correct option is : d) 0.65, current flows left to right.
the answers are: a. 0.24, current flows left to right b. 0.24, current flows right to...
A horizontal length of current-carrying wire is suspended from two identical flexible leads that are under tension due to the weight of the wire. The wire is oriented at right angles to a uniform magnetic field that has a magnitude of 3 T and is directed into the screen of the figure. The length L of the wire is 5 cm and its mass m is 10 g. What current will produce a magnetic force on the wire such that...
