The mathematical importance of this function called the potential is that it is a scalar quantity, and the potential at any point due to any number of point charges ql, q2, q3, &c., distributed in any manner, is the sum of them separately, or qi/xl+q2/x2+q3/x3+&c. =F (q/x) =V (17), where xi, x2, x 3, &c., are the distances of the respective point charges from the point in question at which the total potential is required.
In this issue's QL User, Quentin Lowe gives us his first impressions of Sir Clive's new micro.
Sinclair has matched the QL against other microcomputers on the market, including the BBC Micro.
The module also supports the VT100 communications protocol, giving the QL a valuable new role as a terminal to widely used minicomputers.
Rumors of the QL's demise were quickly scotched as visitors swarmed through the door of Central Hall Westminster.
