For questions 1-7, read the text below and decide which answer (A, B, C or D) best fits each gap
There were many (1)__________ in the 19th and the beginning of the 20th century - like those of J. J. Thomson (1881), Oliver Heaviside (1888), George Frederick Charles Searle (1896), - to understand how the mass of a(n) (2)__________ object varied with the velocity. Because the electromagnetic field carries part of the momentum of a moving charge, it was suspected that the mass of an electron would vary with velocity near the speed of light.
Following Searle (1896), Wilhelm Wien (1900), Max Abraham (1902), and Hendrik Lorentz (1904) concluded that the velocity dependant electromagnetic mass of a body (3)_______ is m = (4 / 3)E / c2. According to them, this relation applies to the complete mass of bodies, because any form of inertial mass was considered to be of electromagnetic (4)________. Wien went on by stating, that if it is assumed that gravitation is an electromagnetic effect too, than there has to be a(n) (6)________ proportionality between (electromagnetic) inertial mass and (electromagnetic) gravitational mass. To explain the stability of the matter-electron configuration, Poincarй in 1906 introduced some sort of pressure of non-electrical nature, which contributes the amount − (1 / 3)E / c2 to the mass of the bodies, and (7)_________ the 4/3-factor vanishes.
