2. A proton has a mass of 1.67 x 10-27 kg and a charge of 1.60 x 10-19 C. What is the weight (gravitational force) on a single proton at Earth’s surface?
To calculate the weight (gravitational force) on a single proton at Earth’s surface, we need to use the formula:
Weight = mass * acceleration due to gravity
First, we need to find the acceleration due to gravity on Earth's surface. This value is represented by 'g' and is approximately 9.8 m/s².
Now, let's substitute the values into the formula:
Weight = (1.67 x 10^-27 kg) * (9.8 m/s²)
To perform the calculation, multiply the mass of the proton (1.67 x 10^-27 kg) by the acceleration due to gravity (9.8 m/s²):
Weight = 1.63 x 10^-26 N
The weight of a single proton at Earth's surface is approximately 1.63 x 10^-26 Newtons.
