An inclined plane making an angle \(30^{\circ}\) with the horizontal is placed in a uniform horizontal electric field of \(100 \mathrm{Vm}^{-1}\) as shown in the figure. A small block of mass \(\mathrm{I} \mathrm{kg}\) and charge, 0.01C is allowed to slide down from rest from a height, \(h=1 \mathrm{~m}\). If the coefficient of friction is 0.2 , then the acceleration of the block is nearly,
(Acceleration due to gravity, \(g=10 \mathrm{~ms}^{-2}\) )

  1. A \(1.3 \mathrm{~ms}^{-2}\)
  2. B \(2.3 \mathrm{~ms}^{-2}\)

Answer & Solution

Correct Answer

(B) \(2.3 \mathrm{~ms}^{-2}\)

Step-by-step Solution

Detailed explanation

According to the question, an inclined plane is making an angle of \(30^{\circ}\) with the horizontal, placed in a uniform electric field of \(100 \mathrm{~nm}^{-1}\). It can be such in the figure that a block of mass \(m\) is sliding down from rest at height \(h\). From the…
