How do charge, polarization, and Coulomb's law combine to allow a charged object to attract a neutral object? Two charged particles exert an electrostatic force of 20n on each other. What will the magnitude of the electrostatic force be if the distance between the charges is reduced to one-...
The result, he says, is that any object that is hit by a beamproduces a thrust that is proportional to the mass of the object. Wave dirkcollett grove in adjusting a laser aiming device, said he knocked down hisexperimental device has been shown capable of 1 km, he claimed that the dev...
The Earth is again approximated as something that has an inexhaustible supply of free positive and negative charge that always remains uncharged. Connecting the metal plate to ground is what happens when so much charge accumulates on the cloud, that the air momentarily becomes "conducting", and ...

TMV had also been the subject of many biophysical experiments before the Second World War, with an important impact on the development of cutting-edge analytical technologies and instruments. Its rod-like, charged structure was deduced from double refraction observed by Takahashi and Rawlins for virus...
