a
The electric forces acting on them will be equal
b
The magnitudes of the forces will be equal
c
Their accelerations are not equal
d
The magnitudes of their accelerations will be equal
detailed solution
Correct option is W
Electrostatic force=F=qE acceleration=a = Fm=qEmForce will be same as charge of proton and electron are same in magnitude but opposite in directionacceleration is more for electron as its mass is very less compare to proton. me=mp1837Talk to our academic expert!
