Dear student,

It seems that you are having trouble with your electric field homework. Let's start by reviewing the given information: acceleration = 1e18 m/s^2. This means that an object is experiencing an acceleration of 1 x 10^18 meters per second squared. To solve for the electric field in each scenario, we can use the formula E = m*a, where E is the electric field, m is the mass of the object, and a is the acceleration.

For the first scenario, we are given the mass of the object (0.1 kg) and the acceleration (1e18 m/s^2). Plugging these values into the formula, we get E = (0.1 kg)*(1e18 m/s^2) = 1e17 N/C. This means that the electric field in this scenario is 1 x 10^17 Newtons per Coulomb.

For the second scenario, we are given the electric field (1e5 N/C) and the mass of the object (1 kg). We can rearrange the formula to solve for acceleration: a = E/m. Plugging in the values, we get a = (1e5 N/C)/(1 kg) = 1e5 m/s^2. So the acceleration in this scenario is 1 x 10^5 meters per second squared.

For the third scenario, we are given the electric field (1e-3 N/C) and the acceleration (1e18 m/s^2). Again, we can rearrange the formula to solve for mass: m = E/a. Plugging in the values, we get m = (1e-3 N/C)/(1e18 m/s^2) = 1e-21 kg. This means that the mass of the object in this scenario is 1 x 10^-21 kilograms.

I hope this helps you understand how to approach these types of problems. Keep practicing and don't hesitate to ask for help when needed. Good luck with your studies!

Sincerely,
