A) \[{{a}_{A}}>{{a}_{B}}\]
B) \[{{a}_{A}}<{{a}_{B}}\]
C) \[{{a}_{A}}={{a}_{B}}\ne 0\]
D) \[{{a}_{A}}={{a}_{B}}=0\]
Correct Answer: C
Solution :
[c] As force on short wire AB acts upward and the torque of magnetic force about c.m. is in clockwise sense, so acceleration of point A, \[{{a}_{A}}={{a}_{cm}}+\alpha I/2\] and for B,\[{{a}_{B}}={{a}_{cm}}-\alpha I/2.\]Thus \[{{a}_{a}}>{{a}_{B}}.\]You need to login to perform this action.
