Question

Three forces act on a particle that moves with unchanging velocity v = 21 - 7). Two of the forces are
F = 2i + 3j - 2k and F2 = -5î + 8j – 2k What is the third force?​

Answer 1

Answer:

Explanation:look friend if the particle has unchanging/constant velocity it means that it's accelaration is0 because accelaration is nothing but change in velocity so subsequently net force acting on particle is 0 because F =ma so the Third force will cancel out the resultant of these two forces I.e 3i-11j+4j
