The electrostatic force \left(\overrightarrow{\mathrm{F}_1\right) and magnetic force \left(\overrightarrow{\mathrm{F}_2\right) acting on a charge q moving with velocity v can be written:
Options
- A\overrightarrow{\mathrm{F}_1=\mathrm{q} \overrightarrow{\mathrm{V}} \cdot \overrightarrow{\mathrm{E}}, \overrightarrow{\mathrm{F}_2=\mathrm{q}(\overrightarrow{\mathrm{B}} \cdot \overrightarrow{\mathrm{V}})
- B\overrightarrow{\mathrm{F}_1=\mathrm{q} \overrightarrow{\mathrm{B}}, \overrightarrow{\mathrm{F}_2=\mathrm{q}(\overrightarrow{\mathrm{B}} \times \overrightarrow{\mathrm{V}})
- C\overrightarrow{\mathrm{F}_1=\mathrm{q} \overrightarrow{\mathrm{E}}, \overrightarrow{\mathrm{F}_2=\mathrm{q}(\overrightarrow{\mathrm{V}} \times \overrightarrow{\mathrm{B}})
- D\overrightarrow{\mathrm{F}_1=\mathrm{q} \overrightarrow{\mathrm{E}}, \overrightarrow{\mathrm{F}_2=\mathrm{q}(\overrightarrow{\mathrm{B}} \times \overrightarrow{\mathrm{V}})
Correct answer
C. \overrightarrow{\mathrm{F}_1=\mathrm{q} \overrightarrow{\mathrm{E}}, \overrightarrow{\mathrm{F}_2=\mathrm{q}(\overrightarrow{\mathrm{V}} \times \overrightarrow{\mathrm{B}})
Step-by-step solution
Electrostatic force, \overrightarrow{\mathrm{F}_1=\mathrm{q} \overrightarrow{\mathrm{E}}
Magnetic force, \overrightarrow{\mathrm{F}_2=\mathrm{q}(\overrightarrow{\mathrm{V}} \times \overrightarrow{\mathrm{B}})
