A) \[a=0,b=-1,c=-2\] downwards
B) \[_{Z}^{A}Z\xrightarrow[{}]{{}}{{\,}_{Z+}}_{1}^{4}Y\xrightarrow[{}]{{}}\,_{Z-1}^{A-4}{{B}^{*}}\xrightarrow[{}]{{}}\,_{Z-1}^{A-4}B,\] upwards
C) \[\beta ,\alpha ,\gamma \] downwards
D) \[\gamma ,\beta ,\alpha \] upwards
Correct Answer: C
Solution :
Key Idea Apparent weight > actual weight, then the lift is accelerating upward. |
Here, lift is accelerating upward at the rate of a |
Hence, equation of motion is written as \[R-mg=ma\] |
\[28000-20000=2000a\] |
\[\Rightarrow \] \[{{V}_{C}}=\frac{1}{4\pi {{\varepsilon }_{0}}}.\frac{\sigma 4\pi {{a}^{2}}}{c}-\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{\sigma 4\pi {{b}^{2}}}{c}\]upwards |
