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: B
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 \[=\frac{\sigma }{{{\varepsilon }_{0}}}\left( \frac{{{a}^{2}}}{c}-b+c \right)\frac{\sigma }{{{\varepsilon }_{0}}}(2a)\,(\because c=a+b)\]\[{{V}_{C}}=\frac{1}{4\pi {{\varepsilon }_{0}}}.\frac{\sigma 4\pi {{a}^{2}}}{c}-\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{\sigma 4\pi {{b}^{2}}}{c}\]upwardsYou need to login to perform this action.
