Another charge particle B is palced on the slope at an angulare position β measured from the line of greatest slope passing through the position of the first particle. The coefficient of froction between the particle B and the slope is μ(μ<tanα) .For the particle at B to stay in equilibrium what would be the maximum value of the angle β ?

A uniform nonconducting rod of mass ma and length l and the charge on the drop is Q. What will be the number n of the last drop taht can still enter the sphere? Electrically charged drops of nercury fall from an altitude h into a sperical metal vessel of radius R. There is a small opening in the upperapart of the vessel. The mass of eanc drop is m In a horizontal unifrom electirc field nonconductive walls the bead move Two identical small balls each have a mass m and charge q. When placed in a hemispherical bowl of radius R with frictionless
