It depends on the type of interference.
For constructive interference, add the amplitudes to get |35 + 41| = 76 units.
For destructive, subtract them |35 - 41| = 6 units
Answer:
BC
Explanation:
A) In a uniform field , dipole can remain in rotational equilibrium as well as linear equilibrium . So statement is wrong.
A dipole whose moment vector is not aligned with a uniform electric field will twist around toward being aligned. Moment vector is aligned along the axis of the dipole. In this position torque acting on the dipole is zero so it is in rotational equilibrium.
On the dipole only torque acts and no net force acts in case of uniform electric field. In case of non uniform magnetic field, both torque and force exists. each pole experiences electric force of equal magnitude.

Answer:
-7.072 °
Explanation:
According to the given data, angular position is defined by
angular position = 17 ° cos( wt)
Where,
w is the angular frequency
w = √(g/L)
where,
L= length and g = acceleration due to gravity =>9.8m/s²
angle = 17 ° cos( √(g/L) t) ---->(note to solve your calculate should be in radian mode)
At t=0.35s
angle = 17 ° x -0.416
angle= -7.072 °
Therefore, the angular position of the pendulum at t = 0.35s is -7.072 °
