A body of mass \(4 \mathrm{~kg}\) is accelerated upon by a constant force, travels a distance of \(5 \mathrm{~m}\) in the 1st second and a distance of \(2 \mathrm{~m}\) in the \(3 \mathrm{rd}\) secon(d)The force acting on the body is
- A \(2 \mathrm{~N}\)
- B \(4 \mathrm{~N}\)
- C \(6 \mathrm{~N}\)
- D \(8 \mathrm{~N}\)
Answer & Solution
Correct Answer
(C) \(6 \mathrm{~N}\)
Step-by-step Solution
Detailed explanation
We know that, displacement travelled by a moving body with constant acceleration a in \(n\)th second, \[ s_{n}=u+\frac{1}{2} a(2 n-1) \] For first second, \(n=1\)…

- Two conducting spherical shells A and B of radii 4 cm and 6 cm respectively are placed with their centres 17 cm apart in air. Initially, sphere A was given a \(-20\) nC charge while sphere B was uncharged. The spheres are then connected by a long thin conducting wire and allowed to reach electrostatic equilibrium. Assuming no charge is lost to the surroundings, the final charge on sphere A and the ratio of magnitude of electric field intensity at the surface of sphere B to that of sphere A is given by:COMEDK 2026 Medium
