A long, straight wire lies along the x-axis and carries current I=55.0 A in the +x-direction. A small particle with mass 4.00 x 10-6 kg and charge 8.00 x 10-3 C is traveling in the vicinity of the wire. At an instant when the particle is on the y-axis at y = 9.00 cm, its acceleration has components a = -5.00 x 103 m/s² and ay = +9.00 x 103 m/s² Part A ۵ At that instant what are the x- and y-components of the velocity of the particle?

98% ?. l3Ī 7 I 16:58 Month 1.pdf Q1:- The coplanar force system shown in Figure below is subjected to a couple moment (M) and three forces. Two forces are known in magnitude and direction and shown in the Figure (150 N and 60 N). The third force is passing through the center of the semi-circle (point C). The resultant of all these forces is a single couple (750 N.m) counterclockwise. a) Determine the magnitude and direction of the third force. b) Determine the magnitude of moment (M). Replace the couple (M) by two vertical equal forces acting at D and E. d) Replace the force (150 N) by and single force at D and a couple. Radius = 5 m 150 N E В M 60 N 4 A F.
