Answer:
(d) 2 pF
Explanation: the charge on capacitor is given by the expression
Q=CV
where Q=charge
C=capacitance
V=voltage across the plate of the capacitor
here we have given Q=500 pF, V=250 volt
using this formula C=
=500×
×
=2×
=2 pF
Answer:
0.1 nm
Explanation
Potential deference of the electron is given as V =150 V
Mass of electron 
Let the velocity of electron = v
Charge on the electron 
plank's constant h =
According to energy conservation 

Now we know that De Broglie wavelength 
Answer:
The axis of motion that is parallel to the spindle axis is always the Z-axis.
Explanation:
Z-Axis Which axis is which depends on the orientation of the spindle.
If the spindle is vertical (Figure 2.1), the Z-axis is vertical. Either the quill or the knee of a vertical spindle mill will move when a Z-axis command is executed.
This is the best answer I could give you, maybe you could show us a pic of the question so we see all the possible choices?
