Question

1. Which of the following can cause a charged particle to accelerate?

A. An Electric field

B. A gravitational field

C. A neutron field

D. (A) and (B)

2. How much electric charge does an electron have compared to a proton?

A. None

B. The same amount

C. The same amount, just the negative kind.

D. Only about 1/2000th as much

Answer 1

(1) Option (D) is the correct answer.

Explanation -

Electric field cause an charge particle to accelerate because it exerts is force F = E*q on the charged particle.

Also, gravitational field exerts a force F' = m*g on the charged particle.

So, option (D) is the correct answer.

(2) Option (C) is the correct answer.

Charge of an electron = -1.602 x 10^-19 C

And, charge on the proton = 1.602 x 10^-19 C

So, both the charges are equal in value but opposite in sign.

Hence, option (C) is the correct answer.
