Positive. The 1st object loses electrons and will thus have an imbalance of charge with loss of electrons.
Answer:
Time period for Simple pendulum, 
Explanation:
The Simple Pendulum
Consider a small bob of mass 
is tied to extensible string of length 
that is fixed to rigid support. The bob is oscillating in the plane about verticle.
Let 
is the angle made by string with vertical during oscillation.
Vertical component of the force on bob, 
Negative sign shows that its opposing the motion of bob.
Taking as very small angle then, 
Let 
is the displacement made by bob from its mean position ,
then, 
so, 
........(1)
Since, pendulum is in hormonic motion,
as we know, 
where 
is the constant and 
.........(2)
From equation (1) and (2)
Since,
