an A4 sheet of paper is being irradiated by a laser giving of about 10g of lift, how much powerful should the laser be? The sheet of paper would eventually fly?
To calculate the power of the laser required to generate 10g of lift on an A4 sheet of paper, we can use the following equation:

Power = (Lift Force x Velocity) / Efficiency

where:

Lift Force = 0.01 kg (10 g)
Velocity = 9.81 m/s² (acceleration due to gravity)
Efficiency = 1 (assuming all of the laser's energy is transferred to the paper)
Substituting the values, we get:

Power = (0.01 kg x 9.81 m/s²) / 1 = 0.0981 watts

Therefore, the laser would need to have a power output of approximately 0.0981 watts to generate 10g of lift on an A4 sheet of paper.

However, it is unlikely that a laser of this power would be able to lift an A4 sheet of paper off the ground, as the weight of the paper itself would be greater than the lift force generated by the laser. Additionally, the laser would need to be precisely aimed at the paper, and the paper would need to be able to absorb the energy from the laser without catching fire or being damaged in other ways. Therefore, it is unlikely that an A4 sheet of paper would fly solely due to the radiation from a laser, regardless of the laser's power output.
9.81 m/s² * 10 = 98.1 m/s², a laser operating at 0.0981 watts would not be sufficient to accelerate a sheet of A4 paper to 10g. Please correct your equation to reflect this.
Alright, can you repeat your question?
