Answer:
The strength of magnetic field is 0.25 T
Explanation:
Time period sec
Mass of proton kg
Charge of proton C
Here proton moves in circular path
Velocity of proton is given by,
Put the value of velocity in above equation,
Now magnetic field is given by,
T
Therefore, the strength of magnetic field is 0.25 T
The work done by the electric force to move a 1 c charge from a to b is
<em>(the voltage at 'b' compared to 'a') volts .</em>
<em></em>
That's because "volt" means "Joule per Coulomb" .
The snail would travel 100mm
Each minutes is 25mm and it took 4 minutes
4 x 25 = 100
or
25+25+25+25=100
Answer:
Please refer to the figure.
q1 is a negative charge, and q2 and q3 are positive charges. So, the force exerted by q1 on q3 is attractive, and the force exerted by q2 on q3 is repulsive, which means F13 is directed towards left, and F23 is also directed towards left.
The net force on q3 is the sum of these two forces:
Since both forces are directed towards left, their sign should be negative.
