Plz can anybody help me with this one

The plates are connected to a battery and then the connection is removed so the two plates are left charged and isolated. If a dielectric material such as a sheet of glass is inserted between the plates: a. no work is done and the energy stored stays constant. b. work is done, increasing the...

Ok thanks a lot for that sir .I got it now .

Hello Sir Plz let me know am i correct or going wrong there mean as fg=mg=4*10=40 and Fe=-Fg=-40N

Sir here as we consider the force of gravity so it need to be +40N NA SIR as we have given that m=4kg, and f=mg =4*10=40, and Fe=-Fg=-40. Is that not right Sir ?

as we are said that the electric force is equal to mass but in oppostie direction then the force that makes the body stantionary in an electric field is F=-mg=-4*10 (g=9.8m/sec^2=10 app), And as E=3*10^6 and using the realtion that F=qE we get q=F/E=-4*10/(3*10^6)=-1.3*10^-5

thanks a lot sir i got that.I am very Thankful for your help .

Hello Sir , i am new to the site and so is not familar of that but i have question and i found u online so wish u to help me with that. Electric forces are used to accelerate small particles (like ink particles in a printers) but consider electrostatic action on macroscopic objects .Suppose...
