... perpendicular electric and magnetic fields are produced, forming a right angle with the ion flight path [3]. There is a specific velocity v such that the ions will feel the magnetic and electric forces equally in modulus and in opposite directions, and will consequently travel in a straight line wit ...

... 3) A electron is located in the midpoint between two fixed charges of –2μC and 4μC. What is the magnitude of the electrons acceleration? Which way does it go? 4) A charged particle carrying charge of -1μC, enters a uniform field of 20N/C. The particle’s motion is perpendicular to the field it enters ...

Suppose the US and Russia were to jointly build a space station with two identical spherical modules (mass, m) to house their crews, and that they are joined by an effectively mass-less conduit (length, d) for astronauts to visit each other. What is the stable orientation of this satellite? (i.e. ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
