What happen If we place negative charge between parallel opposite charge plate ? answer is negative charge attract toward positive plate... Then why Oil drop is suspended btw opposite plates in Millikan's oil drop experiment??

Is anyone here to explain the Result of electric field as potential gradient E= -dV/dr Please Explain this result what is affect on electric intenity as Electric potential difference increase or Decrease And aslo what is affect on electric intenity distance r increase or Decrease Please...

How we calculate permitivity and permeability of free space?

As we know we want to calculate elecrical intenisty at a point P mean we want to to calculate (Force acting on point P per unit positive) so we Draw cylinderical Gaussain surface To calculate intenisty at point P so tell me why we Draw rare part of cylinder behind the plane because we don't...

Assume Electric field intenisty due to Charge +Q around it is constant and it's value is 5N/C and then an other +q0 charge of 2C is place in +Q charge field +q0 experience force that is F=5*2=10N because(F=Eq0) Q:tell me how much force is required to move +q0 charge against electric filed to 1m?

why does an electron not collide with nucleus?? why does an electron not collide with nucleus??

Repulsive Forces in greater than Gravitational Force... Than why electrons does repel each other in same Orbital? i think due to opposite spin which create opposite magnetic field in btw Electrons As we know opposite Magnetic field of lines attracts each other...

Why don't electrons in the same orbital repel each other

As we know 1 molal mean 1 mole of solute dissolve in 1 kg solvent... 1 molar mean 1 mole of Solute dissolve in 1 dm3 solution then how could we effected 1 molar solution with increase in Temperature ?
