Answer to Problem 1STP
C.
Explanation of Solution
Given:
The mass of left box is
The mass of right box is
The length of the board,
Formula used:
The torque is given by,
Where F is the applied force, r is the distance of the point of application of force from the axis of rotation, and
Calculation:
If the fulcrum is at a distance
Now, torque due to boxes will be balanced about the fulcrum. Then,
Conclusion:
Thus, thedistance of the fulcrum from the left side of the board in order to balance the masses horizontally is

- Mick and Rick are twins born on Earth in the year 2175. Rick grows up to be an Earth-bound robotics technician while Mick becomes an intergalactic astronaut. Mick leaves the Earth on his first space mission in the year 2200 and travels, according to his clock, for 10 years at a speed of 0.75c. Unfortunately, at this point in his journey, the structure of his ship undergoes mechanical breakdown and the ship explodes. How old is Rick when his brother dies?arrow_forwardHi, I have canceled, why did you charge me again?arrow_forwardNo chatgpt pls will upvotearrow_forward
