018. A body is moving under the action of two forces
F = 2î – 5j;F; = 3î – 4Î . Its velocity will become
uniform under a third force F, given by
a) sî –ì
b) -5° – j
c) 59 +ĵ
-si+9ị
21-5j +31-4​

Answer 1

For the object to be moving with a uniform velocity the net force on it should be zero (By Newton’s second law) thus the third force should act opposite to the resultant of the given two forces. Which can be found as:
