A rocket with a lift-off mass \(3.5 \times 10^{4} \mathrm{~kg}\) is blasted upwards with an acceleration of \(10 \mathrm{~m} / \mathrm{s}^{2}\). The initial thrust of the blast is \(\left[\text { Take } g=10 \mathrm{~m} / \mathrm{s}^{2}\right]\)
- \(1.75 \times 10^{5} \mathrm{~N}\)
- \(3.5 \times 10^{5} \mathrm{~N}\)
- \(7.0 \times 10^{5} \mathrm{~N}\)
- \(14.0 \times 10^{5} \mathrm{~N}\)
Answer
(C) 7.0 10^ 5 ~N
