It is given that,
Speed of proton,
Acceleration of the proton,
The force acting on the proton is balanced by the magnetic force. So,
m is the mass of proton
B = 0.020875
B = 0.021 T
So, the magnitude of magnetic field is 0.021 T. As the acceleration in +x direction, velocity in +z direction. So, using right hand rule, the magnitude of B must be in -y direction.
B ) position
moving object can have a constant speed ,constant acceleration and no change in the applied force
(when there is no applied force on the object ,it keep its motion uninterruptedly - Newton's first law of motion )
But if an object is moving , it must change its position as if it is still remain in the same position , there can never be a motion at all
Can help cure acne
Studies show that drinking more drinking water can help with blemishes on your face.
The water usually rushes back too enthusiastically, causing a splash – and the bigger the rock, the bigger the splash. The splash then creates even more ripples that tend to move away from where the rock went into the water.
As we know that the current through the battery is given as
here from above equation we know that current will become zero when time elapsed is very large
so here we can say that charge will flow through the battery from t = 0 to t = infinite
now we have
As we know that
