Answer:
C
Sign-Negative
Explanation:
We are given that
Electric field = (Radially downward)
Acceleration=(Upward)
Mass of charge=3 g=kg
1kg=1000g
We have to find the magnitude and sign of charge would have to be placed on a penny .
By newton's second law
Substitute the values then we get
Substitute the values then we get
C
Sign of charge =Negative
Because electric force acting in opposite direction of electric field therefore,charge on penny will be negative.
Given :
Current, I = 3.75 A .
Magnetic Field,
To Find :
The distance from the wire.
Solution :
We know,
Hence, this is the required solution.
