Answer» Solution :use `tau = IA xx B ` and `F = Il xx B` (a) `1.8 xx 10^(-2)` N m along - y direction (b) same as in (a) ( c) ` 1.8 x 10^(-2) N` m along -x direction ( d) `1.8 xx 10^(-2) N` m at an ANGLE of `240^@` with the +x direction (e ) zero ( f) zero Force is zero in each case. Case (e) corresponds to stable, and case (f) corresponds to unstable equilibrium. |
