A rocket is going upwards with accelerated motion. A man sitting in it feels his weight increased 5 times his own weight. If the mass of the rocket including that of the man is 1.0 x 104 kg, how much force is being applied by rocket engine?(Take g = 10 m s-2).
  • a)
    5 x 104 N
  • b)
    5 x 105 N
  • c)
    5 x 108 N
  • d)
    2 x 104 N
Correct answer is option 'B'. Can you explain this answer?

A rocket is going upwards with accelerated motion. A man sitting in it...
As the weight of man increased by 5 times, so acceleration of  the rocket a = 5g = 5 x 10 = 50 m s-2 
Force applied by rocket engine is
F = ma = 1.0 x 104 x 50 = 5 x 105 N

A rocket is going upwards with accelerated motion. A man sitting in it...
Given data:
- Weight felt by the man = 5 times his own weight
- Mass of the rocket including the man = 1.0 x 10^4 kg
- Acceleration due to gravity (g) = 10 m/s^2

Calculating the weight felt by the man:
- Weight = mass x acceleration due to gravity
- Let the man's weight be W and his actual weight be W_actual
- W = 5 x W_actual
- W_actual = mass x g
- W = 5 x mass x g

Calculating the total weight acting on the rocket:
- Total weight = Weight of the rocket + Weight of the man
- Total weight = mass x g + W
- Total weight = mass x g + 5 x mass x g
- Total weight = 6 x mass x g

Calculating the force applied by the rocket engine:
- Using Newton's second law of motion: Force = mass x acceleration
- Force = mass x acceleration due to gravity (upward direction)
- Force = mass x g
- Force = 1.0 x 10^4 kg x 10 m/s^2
- Force = 1.0 x 10^5 N
Therefore, the force being applied by the rocket engine is 5 x 10^5 N, which corresponds to option B.
