Which of the following is not the property of a cathode ray
It casts shadow
It produces heating effect
It produces flurosence
It does not deflect in electric field
A stick of $1 \,m$ is moving with velocity of $2.7 \times {10^8}m{s^{ - 1}}$. ........... $m$ is the apparent length of the stick $(c = 3 \times {10^8}m{s^{ - 1}})$
In Thomson's experiment if the value of $q/m$ is the same for all positive ions striking the photographic plate, then the trace would be
Cathode rays are
${O^{ + + }},\;{C^ + },\;H{e^{ + + }}$ and ${H^ + }$ ions are projected on the photographic plate with same velocity in a mass spectrograph. Which one will strike farthest
Write speed of cathode rays.
