A) \[{{R}_{1}}={{R}_{2}}\]
B) \[{{R}_{1}}=2{{R}_{2}}\]
C) \[2{{R}_{1}}={{R}_{2}}\]
D) \[{{R}_{1}}=4{{R}_{2}}/5\]
Correct Answer: A
Solution :
[a] R is same for both \[\theta \] and \[(90{}^\circ -\theta ).\] If angle w.r.t. Vertical is \[40{}^\circ \] then w.r.t horizontal direction it will be \[90{}^\circ -40{}^\circ =50{}^\circ \].You need to login to perform this action.
