A) \[3.5\times {{10}^{5}}\] N
B) \[7.0\times {{10}^{5}}\] N
C) \[14.0\times {{10}^{5}}\] N
D) \[1.75\times {{10}^{5}}\] N
Correct Answer: A
Solution :
[a] Here, thrust force is responsible to accelerate the rocket, so initial thrust of the blast |
\[=ma=3.5\times {{10}^{4}}\times 10\] |
\[=3.5\times {{10}^{5}}N\] |
