Q. State Coulombs law in electrostatics?
Coulomb's law declares that the force of attraction or repulsion between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. The direction of forces is beside the line joining the two point charges.
A satellite has a mass of 5900 kg and is in a circular orbit 3.0 x 10 5 m above the surface of a planet. The period of the orbit is two hours. The radius of the planet is 4.15 x 1
Is negative mass antimatter? No. There is really no such thing as negative mass. Even antimatter has mass, which is always a positive (that is, greater-than-zero) quantity.
Q. Determine the elapsed time in kinematics? Let S = 1 + c 2 + c 4 + ........ Then, S = 1 + c 2 (1 + c 2 + c 4 +.......... ) S = 1 + c 2 S so, S - c 2 S = 1
Points O, A, and P lie in one as well as the same vertical plane. Point A is 4 . 0 cm due east of point O starting at point O one is able to arrive at point P by going 6 . 0 cm due
newton; N (after Sir I. Newton, 1642-1727) The derived SI unit of force, explained as the force needed to give a mass of 1 kg an acceleration of 1 m/s 2 ; thus it has units of
Forces: If a Force is applied to a body, it will cause that body to move. A body that is already moving will change its speed or direction. Note that the term 'change its spe
