What is the smallest unit of electric charge?
Charge is quantized; it comes in integer multiples of individual small units called the elementary charge, e, about 1.602×10−19 coulombs, which is the smallest charge which can exist freely (particles called quarks have smaller charges, multiples of 13e, but they are only found in combination, and always combine to …
How can we differentiate between a solid sphere and a hollow sphere of the same material and of a same size without weighing?
A solid sphere and a hollow sphere of the same material and of a same size can be distinguished without weighing. by determining their moments of inertia about their coaxial axe. by rolling them simultaneously on an inclined plane. by rotating them about a common axis of rotation.
Which cools faster hollow or solid sphere?
Similarly, equation (3) implies that the rate of change in temperature of the hollow sphere is inversely proportional to its mass, i.e., dThdt∝1mh. Therefore, the hollow sphere cools faster than the solid sphere.
Which expands more solid sphere or hollow sphere?
There are two sphers of same radius and material at the same temperature but one being solid while the other hollow. The expansion in volume with temperature is ΔV=VγΔTorΔV∝ΔT for the given values of V and γ. so hollow sphere will expend more then solid sphere.
What is the charge on a metallic hollow sphere?
When any charge is given to a metallic hollow sphere or a solid sphere the charge distributes such that the net electric field inside the sphere is zero & therefore no charge resides inside the sphere whether it is hollow or solid , all the charges reside at the surface of the sphere .
Do hollow objects hold the same amount of charge as solid objects?
All else being equal, a hollow and a solid conducting sphere hold the same amount of charge . where Q is the amount of charge, C is the ‘capacitance’ of the capacitor and V is the voltage applied between the conducting plates or surfaces of the capacitor.
Which spheres will hold the same maximum charge?
A solid sphere and a hollow sphere having same radius will hold same maximum charge . Why does it happen? – Quora Something went wrong. Wait a moment and try again.
What is the electric field intensity inside a conducting hollow sphere?
A conducting hollow sphere will have the entire charge on its outer surface and the electric field intensity inside the conducting sphere will be zero.
