Statement-1: Total work done by non-uniform electric field on a charged particle starting from rest till any time is non-negative. (assume no other forces act on the charged particle).
Statement-2: The angle between electrostatic force an velocity of the charged particle released from rest in non-uniform electric field is always acute. (assume no other forces act on the charged particle).
Statement-2: The angle between electrostatic force an velocity of the charged particle released from rest in non-uniform electric field is always acute. (assume no other forces act on the charged particle).
View answer and explanation
Correct option: C
Statement-1 is true, Statement-2 is false
Option C is correct because Statement-1 is true (work done is non-negative), but Statement-2 is false (the angle can be obtuse).
