Question
Two forces F2,= (50±0.35)N and F2= (35±0.16)N are acting simultaneously on a body. Find the net resultant force on the body if they are acting in: (i) same direction (ii) opposite direction
Solution
(i) When the two forces are acting in same direction, then
F = F1 + F2

(ii) When the two forces are acting in opposite direction, then
F = F1 - F2

F = F1 + F2

(ii) When the two forces are acting in opposite direction, then
F = F1 - F2
