force A is added to two force B=ci-2j+4k and c=2i+3j-6k newton and give unit vector force allow the x axis as their resultant find Acceleration of 5kg body lfA act on the body

Answer 1

If A = pi+qj+rj then
p+c+2 = 1
q-2+3 = 0
r+4-6 = 0
no idea what c is, because of the many typos.
as for the acceleration, F=ma
