TS EAMCET · Physics · Magnetic Effects of Current
Velocity and acceleration vectors of charged particle moving perpendicular to the direction of a magnetic field at a given instant of time are \(\overrightarrow{\mathbf{v}}=2 \hat{\mathbf{i}}+c \hat{\mathbf{j}}\) and \(\overrightarrow{\mathbf{a}}=3 \hat{\mathbf{i}}+4 \hat{\mathbf{j}}\) respectively. Then the value of \(c\) is
- A \(3\)
- B \(1.5\)
- C \(-1.5\)
- D \(-3\)
Answer & Solution
Correct Answer
(C) \(-1.5\)
Step-by-step Solution
Detailed explanation
When a charged particle moves perpendicular to the magnetic field, it follows a circular path. On the circular path its velocity and acceleration will be at right angle to each other. Given,…
