Magnetic Effects Of Current Question 276
Question: Lorentz force can be calculated by using the formula [MP PET 1994, 2002, 03; CBSE PMT 2002]
Options:
A) $ \overrightarrow{F}=q,(\overrightarrow{E}+\overrightarrow{v}\times \overrightarrow{B}) $
B) $ \overrightarrow{F}=q,(\overrightarrow{E}-\overrightarrow{v}\times \overrightarrow{B}) $
C) $ \overrightarrow{F}=q,(\overrightarrow{E}+\overrightarrow{v}\cdot \overrightarrow{B}) $
D) $ \overrightarrow{F}=q,(\overrightarrow{E}\times \overrightarrow{B}+\overrightarrow{v}) $
Show Answer
Answer:
Correct Answer: A
Solution:
Lorentz force is given by $ \overrightarrow{F}=\overrightarrow{F_{e}}+\overrightarrow{F_{m}}=q\overrightarrow{E}+q(\overrightarrow{v}\times \overrightarrow{B})=q[\overrightarrow{E}+(\overrightarrow{v}\times \overrightarrow{B})] $
