1.Which of the following is incorrect?a.When E⃗\vec{E}E is parallel to B⃗\vec{B}B, a charged particle in motion may move in a straight path with acceleration related to E⃗\vec{E}E as a⃗=kE⃗\vec{a} = k\vec{E}a=kE, where kkk is a positive constantb.When E⃗\vec{E}E is parallel to B⃗\vec{B}B, a charged particle in motion may move on a helix with increasing pitchc.When E⃗\vec{E}E is perpendicular to B⃗\vec{B}B, a charged particle in motion may move on a straight path with acceleration related to E⃗\vec{E}E as a⃗=−kE⃗\vec{a} = -k\vec{E}a=−kE, where kkk is positived.When E⃗\vec{E}E is perpendicular to B⃗\vec{B}B, a charged particle in motion may move on a cycloidLogin to continueOnly logged in users canattempt or see the solution.
