A wedge is moving rightwards on which a block of mass 10 kg is placed on it. Friction coefficient between the eedge and the block is 0.8. Select correct alternative (s) among the following options. [take `g=10(m)/(s^(2))`]

Options

A. If wedge is moving with constant velocity then friction acting on block is `64N`
B. If wedge is moving with constant velocity then acceleration of block is zero
C. If wedge is moving with `veca=2(hati)m//s^(2)` then friction acting on block is `44N`
D. If wedge is moving with `veca=10(hati)m//s^(2)` then friction is `20N`, downward on the block along the inclined.

Explanation
