A) doubled
B) tripled
C) quadrupled
D) 8 times the original value
Correct Answer: C
Solution :
The dimensions of angular momentum are \[J=[M{{L}^{2}}{{T}^{-1}}]\] When doubled \[J'=[2M{{(2L)}^{2}}{{(2T)}^{-1}}]\] \[\Rightarrow \] \[J'=4[M{{L}^{2}}{{T}^{-1}}]=4J\] Unit of angular momentum is quadrupled.
