What does gravitational force depend on?
Gravitational force depends on mass and distance.
Therefore, the formula for calculating gravitational force among two objects with a given distance: G [(mass 1) (mass 2)]/distance squared. G is universal gravitational constant: 6.67x10 raised to -11 power.
For a very every case the moment of inertia of a one particle about an axis is given by, I = mr 2 Here, m is the mass of the particle and r its distance from the axis under
A transformer has 1200 primary turns and 200 secondary turns. The primary and secondary resistances are 0.2Ω and 0.02Ω respectively and the corresponding leakage reactances a
Screw gauge works on the rule of screw. It has a linear scale called as the main scale, and another scale called as the circular scale. The circular scale can be moved by a head sc
Consider an electron in a simple one-dimensional periodic potential. The energy of the electron will vary periodically due to the influence of the periodic potential, and can be de

What is the measure of the force of gravity on an object? Force is the vector product of mass and acceleration: F = ma. Weight is a special case of that formula, where you subs
Can we take a negative test charge to find electric field?
Di - Electric: The insulator used among the plates of a capacitor is known as Di-electric.
Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
