Question

Which force cannot act from a distance ? 

Magnetic

Electrostatic

Gravitational

Frictional

​

Answer 1

Gravitational force

$\huge\pink{\mid{\fbox{\tt{Explanation:-}}\mid}}$

Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy--including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides
