Question

A charge is given velocity perpendicular to uniform electric field, then
Statement I: Initial powerdelivered byelectric field is zero.
Statement II: Path of charged particle is circular.

• A. If both statements are true and statement II is correct explanation of statement I.
• B. If both statements are true but statement II is not the correct explanation of statement I.
• C. If statement I is true but the statement II is false.
• D. If both statements are false.

Answer 1

Answer: (C)

Since electric force and velocity of charge particle is perpendicular to each other, hence initial power delivered by electric field is zero. Also, path of charged particle is parabolic.
