MCQ

With the decrease in the wave length of the incident radiation the velocity of the photoelectrons emitted from a given metal

A
Remains same
✓
Increases
C
Decreases
D
Increases first and then decreases

✓

Answer

Correct option: B.

Increases

As wavelength decrease, frequency increases and hence $K.E$ of photoelectrons increases, thereby increasing the velocity.

While working on a physics project at school physics lab, you require a $4 \,\mu F$ capacitor in a circuit across a potential difference of $1 \,kV$. Unfortunately, $4 \,\mu F$ capacitors are out of stock in your lab but $2 \,\mu F$ capacitors which can withstand a potential difference of $400 \,V$ are available in plenty. If you decide to use the $2 \,\mu F$ capacitors in place of $4 \,\mu F$ capacitor, minimum number of capacitors required are
