Momentum conservation
momentum consv means acceleration of centre of mass is zero, so i want to confirm it in this case...
at the top point when it comes to rest:
1. if we consider both wedge and block(we see the com of both of them), then both the normals cancel out and net force on com in x axis is zero so mom is consv in x axis.
...
Trigonometric series
I tried multiplying and dividing by sin to convert it to double angle but after that I'm stuck, or is this solved by some other way?
capacitor cube
given is a cube where each line has a capacitor of capacitance C. we need to find capacitance along specified points
potential and field
A is def correct
B. E due to induced charges + E due to dipole = 0 so Einduce = -Edipole = given term
C. potential due to induced charges = 0 , potential due to charge on sphere = kQ/R , potental due to dipole = kp/(2r)^2 so net potential at C = kQ/R + kp/4R^2
D. ik Vnet at D = Vind + Vdipole + Vsphere = kp/R^2+ kQ/R + Vind...
