As far as I remember, the first row gave as the lengths in cm, and the second row was corresponding forces.
So I divided the numbers in the second row by corresponding numbers in the first row, and I got something like 0.3 0.6 0.7 and 0.7, which gave me an average of 0.6 approximately, so I went for 0.6N/cm. Was it like the question gave us the equilibrium length and we had to subtract the length from the values of the first row?
In the wire and positive charge moving away from the wire question, I clearly remember that the question ignored all the forces EXCEPT for electric and magnetic forces. So if the wire had a static positive charge, a force directing away from the wire is applied to the positive point charge. Am I right?
For the question that asked for (an) option(s) that would be accelerated toward the direction of the electric field between two oppositely charged parallel plates, the answer was only proton right? I saw some people talking about electrons but didn't the question ask for a particle that would accelerate toward the direction of the electric field?
For the box moving down an inclined plane, all three forces act on the box right?
Hope you guys did well and get a score higher than your expectation!
