A) Object P
B) Object Q
C) Both objects will possess same energy
D) None of these
Correct Answer: A
Solution :
For object \[\text{P}\]\[\text{m =}\,\text{2kg,}\]\[\text{v = 10m/sec}\] \[\text{K}\text{.E}{{\text{.}}_{\text{P}}}=\frac{1}{2}m{{v}^{2}}\] \[=\frac{1}{2}\times 2\times {{10}^{2}}\] \[=100J\] For object Q \[m=3kg,v=7m/\sec \] \[K.E{{.}_{Q}}=\frac{1}{2}\times 3\times {{7}^{2}}\] \[=73.5J\] So, \[K.E{{.}_{P}}>K.E{{.}_{Q}}\]
