As per the question, the resistor system contains two resistors.
The two resistors are denoted as
We are asked to calculate the effective resistance in terms of
The two resistors can be connected in two ways.
CASE-1: Let the resistors are connected in series.
When the resistors are connected in series, the effective resistance is the algebraic sum of the individual resistors.
Hence, the effective resistance [ans]
CASE-2: Let the resistors are connected in parallel.
The effective resistance is calculated as follows-
⇒ [ans]
Answer:
option (B)
Explanation:
mass of proton, m = m
charge of proton, q = e
Time period, T = T
Initially the speed of proton is v.
The time period of the proton when it is moving in magnetic field perpendicular to the direction of magnetic field is given by
Where, r be the radius of circular path.
The relation between r and the speed v is given by
Where, B be the strength of magnetic field. Substitute this value of r in the expression of time period
Here, we observe that the expression for the time period is independent to v and r so, as we change the velocity, the time period remains same.
