The resistance of the coil of a pivoted-coil galvanometer is 8.37 Ω, and a current of 2.94×10−2 A causes it to deflect full scale. We want to convert this galvanometer to an ammeter reading 21.0 A full scale. The only shunt available has a resistance of 3.00×10−2 Ω.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
