A rod of m = 0.14 kg and Z = 0.75 m is on a ramp of two parallel rails with angle 0= 290 with respect to the horizontal. The current on the rod is / = 0.085 A, pointing into the screen as shown. A uniform magnetic field B = 0.75 T which points upward is applied in the region. Ignore the friction on the rails. B A 50% Part (a) Calculate the component of the acceleration of the rod along the parallel rails in m/s . Take up the ramp to be the positive direction. 4 50% Part (b) What direction is the rod moving if it started from rest? O Up the ramp. ODown the ramp. Submit Hint Feedback I give up! $4. - -1
