Closest distance of approach due to Magnetic Field of wire
Consider an infinite wire carrying current I and a particle of mass m, charge q and at a distance a from the wire move with velocity v parallel to the direction of current. Due to the magnetic field, the particle gets attracted to the wire, and it turns around at a distance x. Find the value of x.I don't get the mathematical approach we should take in this question. I tried qv_xB=mv_ydv_y/dy and so on, but it doesn't give a clear answer....
Functions, number of conditional one-one functions
All I've got is that all of the plus terms need to be added to a maximum of 10, so f(a) can only be till 5, f(c) can only be till 3 and f(d) can be till 10.
Also that all the plus terms can't be added up to 1 or 2 in any way since one-one gets violated.
Not sure how to proceed....
Vectors, given dot and cross product equations
I haven't looked at the solution, I want to know how to think about these types of problems
solutions solutions
i don't understand when to use this formula given below, and when to use rlvp, like what's the difference?
capacitance
how to approach this q? i found charges on each capacitor but which charge do we use for finding the capacitance
