Solve the Problem $\mathrm { m }$ And Charge $\mathrm { q }$

question 166

Multiple Choice

Solve the problem.
-A charged particle of mass $\mathrm { m }$ and charge $\mathrm { q }$ moving in an electric field E has an acceleration a given by $\mathrm { a } = \frac { \mathrm { qE } } { \mathrm { m } }$ ,
where $\mathrm { q }$ and $\mathrm { E }$ are constants. Find $\frac { \mathrm { da } } { \mathrm { dm } }$ .

• A) \(\frac { d a } { d m } = \frac { q E } { m ^ { 2 } }\)
• B) \(\frac { d a } { d m } = - \frac { m } { q E }\)
• C) \(\frac { \mathrm { da } } { \mathrm { dm } } = \mathrm { qEm }\)
• D) \(\frac { d a } { d m } = - \frac { q E } { m ^ { 2 } }\)
