Usually the unit of measurement of velocity is meters per second or m/s
Answer:
The magnitude and direction of the acceleration of the particle is
Explanation:
Given that,
Mass
Velocity
Charge
Magnetic field
We need to calculate the acceleration of the particle
Formula of the acceleration is defined as
We need to calculate the value of
Now, put the all values into the acceleration 's formula
Negative sign shows the opposite direction.
Hence, The magnitude and direction of the acceleration of the particle is
i think it’s B. sorry if i’m wrong
Answer:
Induced emf in the coil, E = 0.157 volts
Explanation:
It is given that,
Number of turns, N = 100
Diameter of the coil, d = 3 cm = 0.03 m
Radius of the coil, r = 0.015 m
A uniform magnetic field increases from 0.5 T to 2.5 T in 0.9 s.
Due to this change in magnetic field, an emf is induced in the coil which is given by :
E = -0.157 volts
Minus sign shows the direction of induced emf in the coil. Hence, the induced emf in the coil is 0.157 volts.
