NEET Physics Electrostatic Charges and Fields MCQs

A proton and an alpha particle, both initially at rest, are accelerated through the same potential difference $V$. If the proton acquires a velocity $v_p$, what is the velocity of the alpha particle?

An electron enters a uniform electric field $E$ with an initial velocity $v_0$ perpendicular to the field. What is the trajectory of the electron?

Two identical charged particles are projected into a uniform electric field. Particle A is projected at an angle $heta$ with the field, while particle B is projected perpendicular to the field. If both have the same initial kinetic energy, which particle will have a greater range along the direction of the field?

A charged particle of mass $m$ and charge $q$ enters a region of uniform electric field $E$ with a velocity $v$ perpendicular to the field. The time taken by the particle to traverse a distance $d$ along the field direction is:

A proton and an electron are released from rest in a uniform electric field. Which particle will experience a greater magnitude of acceleration?

A charged particle is projected with a velocity $v$ at an angle $heta$ to a uniform electric field $E$. If the particle's velocity becomes perpendicular to the field after time $t$, then what is the initial velocity component perpendicular to the field?

Two concentric conducting spherical shells of radii $a$ and $b$ ($b > a$) carry charges $+Q$ and $-Q$ respectively. The electric field at a distance $r$ from the center, where $a < r < b$, is:

A non-conducting sphere of radius $R$ has a volume charge density $\rho = \rho_0(1 - r/R)$, where $\rho_0$ is a constant and $r$ is the distance from the center. The electric field strength at $r = R/2$ is:

A thin, uniformly charged ring of radius $R$ carries a total charge $Q$. A point charge $q$ is placed at the center of the ring. The force required to move the charge $q$ a small distance $z$ along the axis of the ring is proportional to:

Two point charges $+q$ and $-q$ are placed at a distance $d$ apart. The locus of points where the electric potential is zero is a:
