A) \[5\hat{i}-\hat{j}\]
B) \[-5\hat{i}-\hat{j}\]
C) \[5\hat{i}+\hat{j}\]
D) \[-5\hat{i}+9\hat{j}\]
Correct Answer: D
Solution :
: For uniform velocity, accleration is zero. Hence resultant force will be zero \[\therefore \] \[{{\overrightarrow{F}}_{1}}+{{\overrightarrow{F}}_{2}}+{{\overrightarrow{F}}_{3}}=0\] \[(2\hat{i}-5\hat{j})+(3\hat{i}-4\hat{j})+{{\overrightarrow{F}}_{3}}=0\] Or \[{{\overrightarrow{F}}_{3}}=(-5\hat{i}+9\hat{j})\]You need to login to perform this action.
