  • Option 2)

    T1 > T

  • Option 3)

    T1=T

  • Option 4)

    None

As we learnt,

 

when electric field applied in upward direction -

{T}'=2\pi \sqrt{\frac{l}{g-\left ( \frac{q\epsilon }{m} \right )}}

{T}'> T

- wherein

 

g' = g - \frac{QE}{m}

So new time period 

T_1 = 2\pi\sqrt{\frac{l}{g - \frac{QE}{m}}}

\therefore T_1> T


Option 1)

T1 < T

Option 2)

T1 > T

Option 3)

T1=T

Option 4)

None
