Answer» If A = 2i^-3j^+7k^ B = i^+2k^& C = j^-k^Find A•(B×C)<br>If A = 2i^+3j^+4k^ and B = 4i^+3j^+2k^, find the angle between A and B<br>The work done by a Force F during a displacement r is given by F.r. Suppose a force of 12N acts on a particle in vertically updated directions and the particle is displaced through 2.0 m in vertically downward direction. Find the work done by the force during this displacement.<br>Find the magnitude of √3i^+4j^
