Listing 10 of 22 questions
State what is meant by a field of force. Gravitational fields and electric fields are two examples of fields of force. State one similarity and one difference between these two fields of force. similarity: difference: Two protons are isolated in space. Their centres are separated by a distance R. Each proton may be considered to be a point mass with point charge. Determine the magnitude of the ratio force between protons due to electric field force between protons due to gravitational field . ratio =
