A) \[{{g}_{p}}-\frac{1}{4}R{{\omega }^{2}}\]
B) \[{{g}_{p}}-\frac{3}{4}R{{\omega }^{2}}\]
C) \[{{g}_{p}}-R{{\omega }^{2}}\]
D) \[{{g}_{p}}+\frac{1}{4}R{{\omega }^{2}}\]
Correct Answer: A
Solution :
\[g={{g}_{p}}-R{{\omega }^{2}}{{\cos }^{2}}\lambda \]=\[{{g}_{p}}-{{\omega }^{2}}R{{\cos }^{2}}60{}^\circ \] =\[{{g}_{p}}-\frac{1}{4}R{{\omega }^{2}}\]You need to login to perform this action.
