A cell of negligible internal resistance is connected to a tangent gal...
Explanation:

Single Cell Connected to Tangent Galvanometer
- When a single cell with negligible internal resistance is connected to a tangent galvanometer, it produces a deflection of 30 degrees.
- This deflection is a result of the current flowing through the galvanometer due to the electromotive force (emf) of the cell.

Three Cells Connected in Series
- When three such cells are connected in series and the combination is connected to the same galvanometer, the total emf provided by the cells will be three times that of a single cell.
- Since the internal resistances of the cells are negligible, the total current flowing through the galvanometer will be three times the current produced by a single cell.
- The tangent galvanometer responds to the current passing through it, and the deflection of the galvanometer is directly proportional to the current passing through it.

Deflection in the Galvanometer
- As the current passing through the galvanometer is three times the current produced by a single cell, the deflection produced by the three cells connected in series will also be three times the deflection produced by a single cell.
- Therefore, the deflection in the galvanometer when three cells are connected in series will be 3 x 30 degrees = 90 degrees.
Therefore, the correct answer is (3) 90 degrees.
