calculate the electric field acting on a proton so that proton remains stationary in a space a)2.04*10^-2 b)1.02*10^-7

No electric field will exist.

Explanation:

Given the following:

In other to for the proton to remain stationary in space, the electric field acting on the proton will be 0 or no electric field will exist. From the formulae ;

F = qE ; where q = charge of the particle

E = electric field intensity

The electric field force = F

At a stationary position in space, the electric field intensity = 0

F = qE = q * 0 = 0.

Also according to Heisinberg, measuring the momentum and position of a quantum object becomes more and more uncertain when measured simultaneously.

Here, one of position or momentum is know, measuring the electric field becomes very uncertain.
