2. $$(g-a)$$ upward
3. $$(g-a)$$ downward
4. $$g$$ downward

A particle is projected vertically upwards with a speed $$u$$ and moves under the force of gravity. The distance travelled by the particle during its entire motion (until it returns) is $$d_1.$$ If the force of gravity were to be switched off, and the particle travelled for the same length of time, then the distance travelled is $$d_2.$$ Then,
1.  $$d_2 = d_1$$
2.  $$d_2 = 2d_1$$
3.  $$d_2 = 3d_1$$
4.  $$d_2 = 4 d_1$$
