Provide an Appropriate Response $m$ And Charge $q$ Moving in an Electric Field

question 156

Multiple Choice

Provide an appropriate response.
-A charged particle of mass $m$ and charge $q$ 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) \(\frac { \mathrm { da } } { \mathrm { dm } } = - \frac { \mathrm { qE } } { \mathrm { m } ^ { 2 } }\)
• B) \(\frac { d a } { d m } = q \mathrm { Em }\)
• C) \(\frac { d a } { d m } = - \frac { m } { q E }\)
• D) \(\frac { \mathrm { da } } { \mathrm { dm } } = \frac { \mathrm { qE } } { \mathrm { m } ^ { 2 } }\)
