JEE Main 2 September 2020, Shift 2, Physics Q3
Question 3 of 75 in this shift, Physics question 3 of 25.
A small point mass carrying some positive charge on it, is released from the edge of a table. There is a uniform electric field in this region in the horizontal direction. Which of the following options then correctly describe the trajectory of the mass ? (Curves are drawn schematically and are not to scale).
The figure, in words
Stem figure: a hatched block (table edge) at the left with a small dot (the point mass) at its top-right corner; a horizontal arrow labelled E pointing right above it; axes with x pointing right and y pointing down from a point just right of the block. Each option is a small graph with axes y (vertical, arrow up) and x (horizontal).- (1)[figure: graph of y versus x, curve starting at the origin, nearly flat at first and rising increasingly steeply (curving upward)]
- (2)[figure: graph of y versus x, curve starting high on the y axis and falling, flattening out towards the x axis]
- (3)[figure: graph of y versus x, straight line rising from the origin]Official answer
- (4)[figure: graph of y versus x, curve starting at the origin, rising steeply at first then flattening (curving over)]
