Then, you can use the acceleartion for a net force equation on a system consisting of only mass 1. So, there is a force left of F1, but the mass 1 is accelerating at a= (F1-F2)/(m1+m2). Therefore, there must be another tension force acting against the 70 newton force (F1)...
To find the charge on A, the force between the two charges is calculated using the equation F = kq1q2/r Jul 23, 2013 #1 thercias 62 0 Homework Statement Object A has mass 90.0 g and hangs from an insulated thread. When object B, which has a charge of +130 nC, is held ...
By transposing W to the other side of the equation, we can now see that the tension force in the rope is equal to the weight of the object it carries, as also shown above. If we use more ropes to lift the object, the total tension force gets divided up into the ropes. The ...
Note that, usually, physics problems assume ideal pulleys - massless, frictionless pulleys that can't break, deform, or become separated from the ceiling, rope, etc. that supports them. Let's say we have two weights hanging vertically from a pulley in parallel strands. Weight 1 has a mass...
