A dust particle has an excess charge of $4\mathrm{.}0{10}^6$

electrons and a mass of $5\mathrm{.}0{10}^{-8}g.$ It is initially

held at $d=1\mathrm{.}0{10}^{-3}m$ directly above a fixed

object of the same size that is charged with the

same number of electrons. Both objects are in an

evacuated container.

Part A

Determine the maximum height of the dust particle after its release measured from its initial position.

Express your answer with the appropriate units.

Correct

Correct answer is shown. Your answer $6\mathrm{.}523*{10}^{-3}m$ was either rounded differently or used a different number of significant figures than required for this part.

Part B

What quantities can be determined using the given data?

Check all that apply.

the acceleration of the dust particle

the mass of the fixed object

the size of the dust particle

the forces exerted on the dust particle by the stationary charge

Part C

Determine the initial force exerted on the dust particle by the fixed charge.

Express your answer with the appropriate units.

$(2.$

Correct

Correct answer is shown. Your answer $3\mathrm{.}686*{10}^{-9}N$ was either rounded differently or used a different number of significant figures than required for this part.

Part D

Determine the initial acceleration of the dust particle
