Answer:
(a) The current in the wire is 19.89 A
(b) The distance from the wire is 0.159 cm
Explanation:
Given;
magnetic field, B = 2.5 mT
diameter of the wire, d = 1 cm
radius of the wire, r = 0.5 cm = 0.005 m
(a) The current in the wire is calculated as;
(b) The distance from the wire where the magnetic field is 2.5 mT is calculated as;
Answer:
C. contains negatively charged particles
Explanation:
- J.J Thomson placed two opposite charged electric plates around a cathode ray tube which is a sealed glass tube with high vacuum
