Answer:Explanation:SolutionverifiedVerified by TopprCorrect option is A)F=F 1 =F 2 =F 3 Net force of F 1 and F 2 =F 12 = F 2 +F 2 = 2 FF 12 is opposite to the direction ofF 3 Net force of F 12 and F 3 =F net = 2 F−F=F( 2 −1)F net =ma net F net /F=ma net /ma⇒F( 2 −1)/F= aa net a net =a( 2 −1)solution
