WebFeb 5, 2024 · Another major difference between the two forces is that gravitational force can only be attractive, whereas electrostatic could be attractive or repulsive, depending on the sign of charges; unlike charges attract and like charges repel. Is the force between two masses always attractive can it ever be repulsive? Web1. Gravity acts between any two objects, magnetism only between some. 2. Gravity is always attractive, magnetism is sometimes repulsive. 3. At large distances the gravitational force falls off inversely with the distance squared. The magnetic force falls off at large distances at least as fast as inversely with the distance to the fourth power. 4.

WebJan 15, 2024 · Gravity causes the universe to accelerate because gravity is not always attractive. Roughly speaking, the “source of gravity” is the energy density of a fluid plus three times the pressure of that fluid. Ordinary substances have positive energy and pressure, so gravity attracts. WebGravity is always attractive. That is why no matter where we are we feel a pull 'downwards' towards the centre of the earth. However, electrostatic and magnetic forces can be both … ons type of business

WebWhile gravity is always attractive, electromagnetic forces are always repulsive. False The frequency of a water wave gives us its height False In which of the following parameters does a photon of blue light NOT differ from a photon of yellow light, in a vacuum? speed A wave's velocity is the product of the: Webwith quantum gravity should contain self-repulsive states, i.e. states which would feel either a repulsive or vanishing force when placed asymptotically far from an identical copy of ... (1.1) satis es a>1, and it is always attractive if a<1. In the intermediate case a= 1, for which the extremal dyonic black holes are BPS, the force between ... WebThat said, gravity is incredibly weak compared to the other fundamental forces and is the weakest of all of the fundamental forces. Consider this: The entire mass of Earth is needed to hold an iron nail to the ground. Yet with a simple magnet, the force of gravity can be overcome, allowing the nail to accelerate upward through space. iolanthe name
