as mass 0 0160 kg and is 30 0 cm long It pivots without friction about an axis perpendicular nt a in Figure 1 The gravitational force on the bar acts in the y direction The bar is in a ic field that is directed into the page and has magnitude 0 250 B y X X X X X b X X 1 of 1 Part A T What must be the current I in the bar for the bar to be in rotational equilibrium when it is at an angle 30 0 above the horizontal Use the fact that 7 IBL for a uniform bar of length I carring a current I in a magnetic field Express your answer with the appropriate units I 0 84 Submit Part B Previous Answers Request Answer the right Incorrect Try Again 5 attempts remaining the left downward For the bar to be in rotational equilibrium should I be in the direction from a to b orb to a Drag the terms on the left to the appropriate blanks on the right to complete the sentences b n counterclockwise upward A clockwise www a Gravity tends to rotate the bar about point a so the magnetic force must be and to to tend Therefore the to rotate the bar current must flow from Reset Help could not balance to If the current were from to the bar
