A cubical iron block is given a charge of+40mC and placed in vacuum.
Will there be any change in the flux if it is placed under water of dielectric constant 81. Justify.

A cubical iron block is given a charge of+40mC and placed in vacuum. Calculate the net flux due to the charged cube through one face.

Given below are certain changes taking place to the particles during change of state. From this, find out and tabulate the changes in the particles when water boils to form steam and also when steam condenses to form water. distance increases  attractive force decreases energy increases rate of movement increases distance decreases energy decreases attractive force increases rate of movement decreases

A point charge of 2muC is placed at the centre of a cubic Gaussian surface of side 0.5 cm. What is the net flux through the surface? (Given varepsilon_0 , = 8.85x 10^-12C^2 /N/M^2 )
