A Proton Is Placed in an Electric Field of Intensity $10 ^ { 9 }$

Multiple Choice

A proton is placed in an electric field of intensity 800 N/C. What are the magnitude and direction of the acceleration of the proton due to this field? (e = 1.60 × 10^-19 C, m_proton = 1.67 × 10^-27 kg)

A) 7.66 × $10 ^ { 9 }$ m/ $\mathrm { s } ^ { 2 }$ opposite to the electric field
B) 7.66 × $10 ^ { 10 }$ m/ $\mathrm { s } ^ { 2 }$ opposite to the electric field
C) 7.66 × $10 ^ { 10 }$ m/ $\mathrm { s } ^ { 2 }$ in the direction of the electric field
D) 76.6 × $10 ^ { 10 }$ m/ $\mathrm { s } ^ { 2 }$ opposite to the electric field
E) 76.6 × $10 ^ { 10 }$ m/ $\mathrm { s } ^ { 2 }$ in the direction of the electric field
