Hi, this may be really easy but..
I understand that to have an induced e.m.f , we can either have a rate of change of magnetic flux linkage ( ac source ) or cutting of flux ( like a plate oscillating and cutting through a magnetic field produced by a solenoid ). However does cutting of flux...
So if work is done by electric for on the electron ( aka electron moving from a lower to a higher potential plate ) it is positive while the other way round ( electron moving from higher to lower potential plate ) will have a negative work. Am I right ? Then what about it's EPE and KE , is the...
Suppose we have an electron in a uniform electric field by two parallel plates A and B. (Plate A is higher in potential than B), and we have an electron on plate B moving to A, am I right to say that the electron is losing its own EPE to convert it to KE and there is no work done by electric...
Hi, this may be a very trivial question but,
When calculating energy, is it BE(products) - BE(reactants) or is it the other way round?
I have been solving questions and the solutions were products - reactants for some and reactants - products for some.
Also for mass defect , is it mass (...
But if I do include it and say I get a -6000C, and the question then asks me to calculate the energy transmitted , and if I use the formula V=E/Q, wouldn't I end up getting a negative energy?
For example in a calculation for electric force and electric field strength I was told to omit the sign of the charges while for electric potential and electric potential energy I was told to include it in.
Also for F=ma , if my acceleration was a negative one (deceleration) I was also told to...
Hi , this may been asked quite a bit times but I can't really find a solid answer for this.
Do we have to include negative signs during calculations for vectors or scalars?
I have been told by someone that for vector quantity calculations such as Force we do not include the negative sign or...
