Question 1: A) Dinesh studying rail guns has been suggested for launching projectiles into space without chemical rockets. A tabletop model rail gun (Figure 1.) consists of two long, parallel, horizontal rails, l= 6.80 cm apart, bridged by a bar of mass m= 8.00 g that is free to slide without friction. The rails and bar have low electric resistance, and the current is limited to a constant I = 42.0 A by a power supply that is far to the left of the figure, so it has no magnetic effect on the bar. Figure 1 shows the bar at rest at the midpoint of the rails at the moment the current is established. He wishes to find the speed with which the bar leaves the rails after being released from the midpoint of the rails (Hint: you need to draw the figure). (Mo = 4π × 10-¹T.) Jg x V₁ = = 0 m d Figure 1.

In a coplanar force table experiment two forces F1 and F2 is balanced by a third force F3. F1 4 N and it makes 0 degree with the x-axis F2- 4.5 N and it makes 90 degree with the x-axis (which means that it is towards the y-axis) F3 6 N and it makes 275 degrees with the x-axis Calculate resultant force of F1 + F2 using vector addition and compare with F3. Does your results satisfy equilibrium conditions or there is a significant error?
