What do we mean by uniform linear motion?

Question 2

Three charged particles are arranged on corners of a square as shown in Figure OQ23.11, with charge -Q on both the particle at the upper left corner and the particle at the lower right corner and with charge +2Q on the particle at the lower left corner. Suppose the +2Q charge at the lower left corner is removed. Then the magnitude of the field at the upper right corner:
  1.becomes larger.
  2.becomes smaller.
  3.stays the same.
  4.changes unpredictably.

Answer to Question 1

If the ratio of displacement to time remains constant, the motion is uniform as long as
the motion is also in a straight line.
