Question

During which tide there is combined gravitational force of sun and moon on the earth

Answer 1

Answer:

When lunar and solar tides act against each other, the result is unusually small tides, called neap tides. There is a new moon or a full moon about every two weeks, so that's how often we see large spring tides. When the gravitational pull of the Sun and moon are combined, you get more extreme high and low tides.
