If r and r^1 denotes the angles inside the prism having angle of prism 50^ considering that during interval of time from t =0 to t = t , r varies with time as r =10^ + t ^2 . During the time r ^1 will vary with time as
Options
- A40^ + t ^2
- B50^ - t ^2
- C50^ + t ^2
- D40^ - t ^2
Correct answer
D. 40^ - t ^2
Step-by-step solution
aligned & r = r ^1=50^ & 10+ t ^2+ r ^1=50 & r ^1=50-10- t ^2 & =40- t ^2 aligned
