A semicircular loop symmetrical about y axis is positively charged about in the positive x-axis and negatively charged in the negative x- axis. What is the dipole moment of the arramgement ?

An astronmical telescope has an objective of focal length 200 cm and an eyepiece of focal length 10 cm . An observer ajusts the distance of the eyepiece from the objective to obtain the image of the sun on a screen 40 cm behind the eyepiece. The diameter of the sun?s image is 6.0 cm .Find the diameter of the sun. The average earth-sun distance is 1.5x 1011 m.??

A solid sphere of mass m is released from rest from the rim of a hemispherical cup so that it rolls along the surface. If the rim of the hemisphere is kept horizontal, find the normal force exerted by the cup on the ball when the ball reaches the bottom of the cup.

if battery remains connected than charge increases keeping potential difference constant.but as the condition given here is that battery is disconnected .
|
|
|
|
|
No, As the battery is disconnected, the potential difference cannot remain constant, but it will decrease.Electric field lines represent electric field. So even if dielectric is removed electric field lines exit. i hope this helps.feel free for further clarification.rate me, if you found useful.
