| r and r? denote the angles inside an equilateral prism, as usual, in degrees. Consider that during some time interval from \[t=0\] to \[t=t,\,r'\] varies with time as \[r'=10+{{t}^{2}}.\] During this time r will vary as: (Assume that r and r? are in degree): |
 |
A) \[50-{{t}^{2}}\]
B) \[50+{{t}^{2}}\]
C) \[60-{{t}^{2}}\]
D) \[60+{{t}^{2}}\]
Correct Answer: A
Solution :
| [a] In a prism |
| \[r+r'=A\]\[\Rightarrow \] \[r=A-r'\] |
| \[\therefore \] \[r={{60}^{0}}-(10+{{t}^{2}})=50-{{t}^{2}}\] |
