A) \[{{10}^{2}}\] kg
B) \[{{10}^{3}}\] kg
C) \[{{10}^{4}}\] kg
D) \[{{10}^{5}}\] kg
Correct Answer: B
Solution :
Acceleration produced in jet \[=\frac{\text{Change}\,\text{in}\,\text{velocity}}{\text{Time}}\] \[a=\frac{({{10}^{3}}-0)}{10}=100\,m\text{/}{{\sec }^{2}}\] Mass of plane (m)\[=\frac{\text{Force}}{\text{Acceleration}}\] \[=\frac{{{10}^{5}}}{{{10}^{2}}}={{10}^{3}}\,kg.\]You need to login to perform this action.
