An insulated metallic sphere $\left(x\right)$ is charged and is covered by another insulated hollow metallic sphere $\left(y\right)$. If a connection is made between the two,

When ${10}^{19}$ electrons are removed from a neutral metal plate, the electric charge on it (in coulomb) is 

A positively charged glass rod is brought close to a metallic rod isolated from ground. The charge on the side of the metallic rod away from the glass rod will be

A metallic sphere A isolated from the ground is charged to $+50 \mu \mathrm{C}$. This sphere is brought in contact with other isolated metallics sphere B of half the radius of sphere A. The charge on the two sphere will now be in the ratio

As shown in the figure, two particles, each of mass $\text{'}m\text{'}$ tied at the ends of a light string of length $2a$ are kept on a frictionless horizontal surface. When the mid point $\left(P\right)$ of the string is pulled vertically upwards with a small but constant force $F,$ the particles move towards each other on the surface. Magnitude of acceleration of each particle, when the separation between them becomes $2x$ is $\frac{F}{2m}\frac{x}{\sqrt{a^2-x^2}}$

When a positively charged body is brought near the metal disc of a neutral electroscope, its leaves -
