its easy ...keep trying or if u still dnt gt it dis integration is solved in any std physics book...

now you may ask "Why Lorentz force occurs?" or "Why this particular equation of Lorentz force ?" . . . This was an observed phenomenon and that no magnetic force when charged particle moves parallel to magnetic field.

"EMF is induced when magnetic flux(B.A) through a loop changes" Now why does this occur? Initially Faraday observed it and could not explain it. There are 2 types of EMFs induced - 1) motional EMF 2)EMF due to time varying magnetic field. for the first case "HALL EFFECT" related to "Lorentz...

why auroras exist near alaska ?? Its bcoz of something called "Magnetc bottle" phenomenon. Near poles Earth's magnetic field lines converge.

Its better Braeden that you keep a list of all algebraic operations on matrices and formulae on a page while solving coz matrix algebra is confusing

Also remember C.E and E.C are not the same.

C=(C + E^-1)B C=C.B + E^-1.B C(1-B)=E^-1.B Multiplying both sides by E^-1 ; EC(1-B)=B Is it right ?

Guys, let's change the same question a bit. find the solution where no inverse term appears.

in such questions, its better to use the rule that :- (A)(A^-1)=I (identity matrix)

Just equate centripetal acceleration to the gravitational force at that height. Better just remember the formula instead of deriving each time - v = sq root (GM/r) where G = grav constant, M= mass of earth, r = distance from centre of earth

Instead of making a=0 later its better you balance all the forces in horizontal and vertical direction since box is in equilibrium There will be two conditions : 1) F is pushing force 2) F is pulling force if condition (1), the Normal force increases thus increasing friction and just...

Energy radiated per unit time will be given by Stefan-Boltzmann law - dQ/dt = eAσT^4 (σ - Stefan's constant) but here 'T' is to be taken in Kelvin and not degree celsius. and also this is not the energy lost since energy lost = (Energy radiated)-(Energy absorbed) put T value in the...
