CONCEPTUAL: Select the correct statements in the following list.
As more and more capacitors are connected in parallel, the equivalent capacitance of the combination decreases.
As more resistors are added in parallel to a constant voltage source, the power supplied by the source decreases.
A particle carrying a charge of +e travels in a circular path in a uniform magnetic field. If instead the particle carried a charge of +2e, the radius of the circular path would have been one-half the original radius.
A resistor and a capacitor are connected in series to an ideal battery of constant terminal voltage. At the moment contact is made with the battery, the voltage across the capacitor is zero.
An electric current produces magnetic field.
As more and more capacitors are connected in parallel, the equivalent capacitance of the combination decreases.
A charged particle moves across a constant magnetic field. The magnetic force on this particle causes the particle to accelerate.
As more resistors are added in parallel to a constant voltage source, the power supplied by the source decreases.
A horizontal wire carries a current straight toward you. From your point of view, the magnetic field caused by this current circles the wire in a counter-clockwise direction
The voltage across the terminals of a battery when a current flows is called the electromotive force.
If you connect two identical storage batteries together in parallel, and place them in a circuit, the combination will provide twice the voltage.
A particle carrying a charge of +e travels in a circular path in a uniform magnetic field. If instead the particle carried a charge of +2e, the radius of the circular path would have been one-half the original radius.
A resistor and a capacitor are connected in series to an ideal battery of constant terminal voltage. At the moment contact is made with the battery, the voltage across the capacitor is zero.
An electric current produces magnetic field.
Explanation / Answer
Here, the correct statements are:
>>A charged particle moves across a constant magnetic field. The magnetic force on this particle causes the particle to accelerate
as the magnetic force is acting on the particle , it acclerates
>>A horizontal wire carries a current straight toward you. From your point of view, the magnetic field caused by this current circles the wire in
>>A particle carrying a charge of +e travels in a circular path in a uniform magnetic field. If instead the particle carried a charge of +2e, the radius of the circular path would have been one-half the original radius.
as the radius of path is given as r = mv/(B*q)
>>A resistor and a capacitor are connected in series to an ideal battery of constant terminal voltage. At the moment contact is made with the battery, the voltage across the capacitor is zero.
>>
An electric current produces magnetic field.
